Abstract: During the tunneling construction of Nanjing subway, there is the phenomenon of seepage water in Zhujiang Road section of Nanjing city, China. The SASW method is used to investigate and study the features of ground soil layers in Zhujiang Road section of Nanjing city. The investigation results of SASW method demonstrate that there is a low velocity layer of shear wave in SASW data and the low velocity layer is a high water content silty sand soil layer in Zhujiang Road section. Simultaneously, the SASW method is performed to evaluate the degree of compaction subgrade by measuring shear wave velocity. Through comparing the compaction degree measured by sand-cone method with shear wave velocity of SASW method, the relationship formula between shear wave velocity and degree of compaction of coal waste fill subgrade is presented for controlling the quality of compaction subgrade.

Key words: SASW method, shear wave velocity, tunneling construction, compaction subgrade
