南京地铁岩土工程勘察中的问题及改进

针对南京地铁1号线、2号线施工中出现的地质问题,从地铁工程的特点和施工方法出发,分析地铁勘察与日常地面建筑勘察的差异,指出地铁勘察中存在的不足和容易忽视的几个基本问题,提出解决这些问题的对应措施和完善地铁勘察的建议。

Problems Encountered in Geotechnical Investigations for Nanjing Subway Construction

In accordance with the geological challenges encountered during the investigations for Line 1 and Line 2 of Nanjing subway,it has been found that the conventional investigation approaches usually used for at-grade structures are not suitable for underground subway system.Due to the characteristics and construction methods used for subway structures,it is insufficient to provide geotechnical design parameters just by the conventional investigation approach.The paper points out several problems existing in the exploration of subways and puts forward countermeasures to solve these problems to improve the exploration of subways.
