Description
Technical field
The invention belongs to high roadbed engineering Inspection Technique fields, and InSAR technology high roadbed pressures are based on more particularly, to one kind
Solidity detects and sedimentation compensation method.
Background technology
High roadbed engineering is reached required structures by layered rolling backfill in original hillside fields or cheuch
Than the construction work that surrounding topography is obviously higher by, deformation monitoring and the compactness detection of high roadbed engineering are ensured in engineering construction
The indispensable link of two of construction quality.
The sinking deformation monitoring of high roadbed is generally measured using the measurement of the level on the spot and GPS at present, and the measurement of the level on the spot needs
Field labor operation is wanted, and the period is long, it is big to spend, although GPS measurements solve the problems, such as measurement of the level period length, still
It so cannot be satisfied the detection requirement of large area, big scale of construction high roadbed engineering.Therefore, traditional sinking deformation monitoring method, work
Amount is big, efficiency is low, systematic error is big, monitoring site is discrete, is easily influenced by Changes in weather, and it is high to cannot be satisfied the big scale of construction, high-precision
The detection requirement of embankment engineering.In addition, the compactness detection for filling layer during high roadbed fills, in high roadbed generally uses ring
Knife field sampling generally assesses the compacting that level is filled in certain area or range to fill the compactness of a point in layer
It spends, then goes the compactness of equivalent entire high roadbed with each compactness for filling level, be the inspection of " Points replacing surfaces replace body by face "
Survey method, testing result can actual response high roadbed engineering whole compactness it is horizontal, be often depending on the density of detection
And frequency.Accordingly, it is difficult to which objective evaluation filler diversity and Geotechnical Parameter discreteness are to high roadbed engineering entirety compaction quality band
The influence come；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 artificial detection, it can extend and delay the construction period；Finally, after the completion of large area, the construction of big scale of construction high roadbed,
High roadbed is under long-term Gravitative Loads, and sedimentation and deformation would generally occur for high roadbed, and infall process is longer and sedimentation is uneven, in addition
The compactness of the high roadbed needs that also change further increase in infall process, especially for certain crucial, great high roadbeds
It is extremely important that engineering (such as airport high roadbed), which 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 can not evade certainly
Body defect so that compactness testing result and sinking deformation monitoring are deviateed with Practical Project, to cause the benefit of high roadbed
Repay that there are large errors, it is more difficult to establish the relationship between sedimentation and deformation and compactness, construction accuracy demand cannot be met.
