Abamurus Quality Assessment And Research Based On Ground Penetrating Radar And Nondestructive Testing

Abamurus is used widely in our country’s railway construction as a kind of effective measure protecting and strengthening the side slope. But as concealing the project, its inspecting means of quality safely 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 method, it proposes the mode and method on how to process data of quality inspection, Combined the detection principle and data interpretation methods, and then using the RAMAC/GPR in this paper, a feasmle geological radar detecting technology of nondestructive testing and quality evaluation method were summarized, though the inspection of JingGuang and XiangQian railway of29roadcutting abamurus. At last, some abamurus quality assessment will be made in this paper.This paper diminishes and measures the problem of destruction to abamurus, but find out the potential safely hazard of abamurus effectively fast, this has great social effect and economic meaning in railway construction and operation.
