| Abamurus is used widely in our country's road construction as a kind of effective measure protecting and strengthening the side slope. But as concealing the project,its inspecting means of quality safety lags behind relatively. Due to the constructing condition and the geological condition,the quality problem such as size less than designing requirement, wall loose, backfill not compacting and waterlogging threaten the security of the slope project seriously,and the traditional methods are unable to control those effectively .Under this state, the nondestructive inspecting technology becomes one of the most promising methods now .On the basis of expounding geological radar electromagnetic wave communication theory and the reflection, transmission and the main factors which cause energy losing on different interfaces,this paper prove the feasibility of inspecting various quality defects of abamurus; Combined with the Physical model of wall structure of non-destructive testing, it had drawn the basic principle of GPR inspecting the quality defects of subgrade abamurus; On the basis of explaining the data processing basic conception and method, it proposes the mode and method on how to process data of quality inspection,using GprMax to carry on the numerical simulation of the quality defect which offer the basis with interpreting analyzing of the sectional picture of time of GPR and defect identification; Combined the detection principle and data interpretation methods, a feasible geological radar detecting technology of nondestructive testing and quality evaluation method were summarized,though the inspection of S302 LiangHekou to horse bridge abamurus after the earthquake and the LiangWan high-speed abamurus in two areas .This paper diminishes and measures the problem of destruction to abamurus, but find out the potential safety hazard of abamurus effectively fast, this has great social effect and economic meaning in road construction and operation. |
