SOME PROBLEMS CONCERNING THE APPLICATION OF MODERN DYNAMIC TESTING TECHNIQUE TO INSPECTING THE PERFECTION OF THE BOREHOLE INJECTION PILE
Zhan He-ping · Geophysical and Geochemical Exploration · 2002
With some practical examples, this paper has analyzed some common problems encountered in applying the reflection wave method to inspecting the perfection of the borehole injection pile, such as the second pour surface, the groundwater runoff and the loading layer of rock-inset pile, thus providing referential data for further pile inspection work.
