地震方法无损探测挡土墙内部结构的试验研究

EXPERIMENTAL STUDY OF SEISMIC METHOD IN THE NON-DESTRUCTIVE TESTING OF THE INNER STRUCTURE OF RETAINING WALL

地震方法无损探测挡土墙内部结构是地震方法应用于岩土工程的新发展。挡土墙的形态决定了常规地震反射方法受到了限制，改进现有的地面地震反射方法技术和处理技术才能使地震方法更好地解决地质问题。本文对在无损探测挡土墙结构中所采用的地震反射法技术和应用实例进行了讨论。

To use the seicmic method for non-destructive testing of the inner structure of retaining wall is a new development of seismic method applied in geoteohnical engineering. The shape of retaining wall determines the fact that the conventional seismic reflective method will be limited to a cerfain extent. Tqimprove the available surface seismic reflective method and processing technique makes it possible that the seismic method may better solve the geologic problem. In this paper a discussion on the seismic reflective method adopted in the non-destructive testing of the structure of retaining wall,and an application case is presented.
