Solidity is detected and sedimentation compensation method.
Background technology
High roadbed engineering is to be reached required structures by layered rolling backfill in original hillside fields or cheuch
Than the construction work that surrounding physical features is substantially higher by, the deformation monitoring of high roadbed engineering and compactness detection are ensured in engineering construction
The indispensable link of two of construction quality.
The sinking deformation monitoring of current high roadbed is typically measured using the measurement of the level on the spot and GPS, and the measurement of the level on the spot is needed
Field labor operation is wanted, and the cycle is long, spend big, although GPS measurements solve the problems, such as that the measurement of the level cycle is long, but still
Large area, the detection requirement of big scale of construction high roadbed engineering cannot so be met.Therefore, traditional sinking deformation monitoring method, work
Amount is big, efficiency is low, systematic error is big, monitoring site is discrete, easily influenceed by Changes in weather, it is impossible to meet the big scale of construction, high accuracy height
The detection requirement of embankment engineering.In addition, the compactness detection that layer is filled during high roadbed is filled, in high roadbed typically uses ring
Knife field sampling, typically filling in layer a compactness for point fills aspect to assess compacting in certain area or scope
Degree, then the compactness of equivalent whole high roadbed is gone with each compactness for filling aspect, it is the inspection of " Points replacing surfaces replace body by face "
Survey method, its testing result can actual response high roadbed engineering overall compactness level, be often depending on detection density
And frequency.Accordingly, it is difficult to objective evaluation filler diversity and Geotechnical Parameter discreteness are to high roadbed engineering entirety compaction quality band
The influence for coming；Secondly, the compactness detection needs scene that layer is filled in high roadbed is tested, and detection is filled with single-point or monomer
Standard carries out large area, the detection of big scale of construction high roadbed engineering compaction, and engineering cost will certainly be caused unprecedentedly soaring；Meanwhile, by
In the rate limitation of manual detection, can extend and delay the construction period；Finally, after the completion of large area, the construction of big scale of construction high roadbed,
Under long-term Gravitative Loads, high roadbed sedimentation and deformation to high roadbed would generally occur, and infall process is more long and sedimentation is uneven, in addition
The compactness of high roadbed is also changed in infall process, and needs are further to be improved, especially for some crucial, great high roadbeds
It is extremely important that engineering (such as airport high roadbed) needs to compensate the sedimentation and deformation of high roadbed to reach engineering design requirements
's.
As shown in the above, using traditional compactness detection and sinking deformation monitoring method, due to that cannot evade certainly
Body defect so that compactness testing result and sinking deformation monitoring have deviateed with Practical Project, so as to cause the benefit of high roadbed
Repay and there is larger error, it is more difficult to the relation set up between sedimentation and deformation and compactness, it is impossible to meet construction accuracy demand.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned deficiency of the prior art, there is provided one kind is based on
InSAR technology high roadbeds compactness detect with sedimentation compensation method, its method and step is simple, reasonable in design and low cost, uses
Easy to operate, compactness that can be exactly to constructed high roadbed is detected, while to being molded high roadbed in infall process
Loss volume and compactness detected that testing result is accurate, and obtain the loss volume of be molded high roadbed and constructed
Relation between the compactness of high roadbed, by the compensation that high roadbed is molded after sedimentation provides foundation, makes to be molded height after sedimentation and fills out
Side obtains effective compensation, and it is good that the compensation effect of high roadbed is molded after sedimentation, it is ensured that be molded the stabilization after high roadbed is compensated
Property, it is practical.

Relational expression between the compactness of embankment, foundation is provided by the compensation that high roadbed is molded after sedimentation.
6th, during be molded high roadbed is settled, filled out when be molded height and reach settlement stability state, using number
Obtained according to processing equipment and be molded after sedimentation the loss volume and compactness of high roadbed, and according to being molded high roadbed after sedimentation
Loss volume and compactness, and to sedimentation after the high roadbed that is molded compensate, make the high roadbed of constructing after compensation
Elevation reaches high roadbed elevation of top surface of being constructed before settling, while the compactness that part is compensated during high roadbed is molded after sedimentation reaches
The compactness of high roadbed is molded after to sedimentation, is made to be molded after sedimentation after high roadbed obtains effective compensation, and sedimentation and is molded
The compensation effect of high roadbed is good, it is ensured that be molded the stability after high roadbed compensation, practical.
7th, easy to operate and using effect of the invention is good, is to improve detection data accuracy, and each layer is filled by detecting
Compactness, and then ensure it is each fill the quality of layer, so as to finally ensure that the quality of constructed high roadbed body, it is right to eliminate
The finally detection of constructed high roadbed body and the error that exists, and detection efficiency is high, testing result is accurate；In addition, being molded
During high roadbed Settlement, the loss volume and compactness of be molded high roadbed can be detected, obtain drop process
Relational expression between the loss volume of middle be molded high roadbed and the compactness of be molded high roadbed, is filled out by being molded height after sedimentation
The compensation of side provides foundation, makes be molded high roadbed after sedimentation and obtains effective compensation, improve be molded it is steady after high roadbed is compensated
It is qualitative.Thus, the accuracy of detection data can be effectively improved using the present invention, and improve sedimentation compensation efficiency and quality.
In sum, the inventive method step is simple, reasonable in design and low cost, using easy to operate, can be right exactly
The compactness of constructed high roadbed is detected, while the loss volume and compactness to being molded high roadbed in infall process are entered
Row detection, testing result is accurate, and obtains pass between the loss volume of be molded high roadbed and the compactness of constructed high roadbed
System, by the compensation that high roadbed is molded after sedimentation provides foundation, makes to be molded high roadbed after sedimentation and obtains effective compensation, and settle
The compensation effect of be molded high roadbed is good afterwards, it is ensured that be molded the stability after high roadbed compensation, practical.
