摘要

南京地铁珠江路段的掘进施工过程中出现大量的渗水，利用SASW方法对地基土性进行了研究分析，得出南京地铁珠江路段的掘进施工过程中出现大量的渗水是由于高含水率的粉砂土层存在，高含水粉砂土层在SASW的频谱曲线上表现为剪切低速层。同时，利用SASW法对高速公路煤矸石的压实路基填筑的状态进行评价，并与常规的灌砂法测定路基的压实度进行对比分析，研究得出了剪切波波速与压实度的关系式，为高速公路路基填筑工程的质量控制提供了一种快捷有效的检测方法。

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.
