摘要
以增城市某工地为例,对同一根工程桩先后采用高应变法、声波透射法和钻芯法进行检测,并对比分析其桩身完整性结果,再以钻芯法验证检测结果的准确性,表明高应变法对桩身深部缺陷位置较敏感,但对桩身浅部缺陷不敏感且无法确定其性质和范围;声波透射法对缺陷位置的确定较准确,且能界定其范围和程度,但由于声测管埋设的原因可能导致一定的误差。
In this paper,the data of field monitoring and model test was used to analyzed the affection of various factors.It concludes the dynamic stress distribution discipline in layered road system.Based on the existing elastic multilayer theories,we use methods of transfer matrix and visco-elastic equation,the dynamic response of three-dimensional layered road system was obtained.Finally we used Matlab matrix numerical analysis software to calculate,and the result was compared with the data of model test.
