武汉地铁二号线一期工程岩土工程勘察特点分析

Analysis on Geotechnical Engineering Inuestigation Features of the First-phase Project of Wuhan No.2 Subway Line

通过对武汉市轨道交通二号线一期工程沿线区域地质构造、工程地质和水文地质特点的分析,说明了在不同地貌单元和不同地质条件下针对地铁施工工法、进行岩土工程勘察的基本内容和方法,指出了地铁勘察在场地条件、勘察要求、试验内容等方面不同于一般的工业与民用建筑岩土工程勘察工作的特点,并据此合理安排勘察实施方案。

Through an analysis to the features of the regional geology structure, the engineering geology and the hydrology geology of the first-phase project of Wuhan NO. 2 subway line, the basic content and method is showed for geotechnical engineering investigation to the different method for the subway construction under the different physiognomy unit and the different geological condition. In addition, it is pointed out that the features of subway investigation which is different of the general industry and civil construction investigation in aspects on location condition, investigation request and test content. The investigation implementation can be plan reasonably according to these featuers.
