Forward Modeling Study on Elastic Wave Method for Detecting the Quality of Concrete Diaphragm Wall

随着我国城市化建设的快速发展,高层和超高层建筑的急剧涌现,深基坑随之大量出现。在基坑开挖过程中,往往会出现不同程度的基坑围护渗漏,直接影响着工程的进度和施工人员的人身安全。简要分析围护渗漏的一些问题,概括普遍渗漏检测的方法,提出用浅层地震勘探方法,即弹性波法进行渗漏检测。通过正演程序进行不同模型的数值模拟,做相应地震响应的对比讨论分析,表明地震方法可以在一定程序上作为物探法检测渗漏的补充方法。

With the rapid development of urbanization in our country and the surge of high-rise and super high- rise buildings, deep foundation pits appear in large numbers with it. In the process of excavation, it tends to appear different degree of surrounding enclosure osmosis then impacts on the progress of engineering and construction per- sonnel safety directly. Briefly analyze some of the problems of osmosis and summarize common detecting methods for it, the use of shallow seismic exploration method, namely, elastic wave method for osmosis detection are put for- ward. Through the numerical modeling of different models with the written forward program, comparative discussion and analysis of corresponding seismic responses, show that the seismic method can serve as a supplementary method for geophysical exploration method to detect osmosis.
