| Abstract: | PS logging technology is one of the seismic exploration methods. It is also a simple, fast and accurate situ testing technology. In this paper, the principle of single hole method PS logging and its application in railway engineering survey have been studied, including the construction of seismic site classification and seismic classification in railway engineering according to the equivalent shear wave. According to dynamic parameters of rock and soil, rock mass quality has been evaluated and the surrounding rock has been classified. The basic value of bearing capacity of rock and soil has been estimated by using shear wave velocity method. The application effect of PS logging technology in geotechnical engineering survey and design has been illustrated through the engineering example of Qingdao airport tunnel site. |
