天津地区岩土工程勘察中地下水重点问题分析

Analysis of critical issue of groundwater in geotechnical engineering investigation in Tianjin area

地下水勘察是岩土工程勘察的一项重要任务。结合天津地区气候条件和浅层地下水水文地质条件,对地下水腐蚀性评价所涉及的环境类型和干湿交替作用的确定进行了研究,解决了地下水腐蚀性评价中存在的主要问题;对抗浮设防水位的确定进行了分析,得到不同情况下抗浮设防水位的确定方法。

Groundwater investigation plays a significant role in the field of geological engineering investigation. Based on the feature of regional climate and hydrogeology of shallow groundwater in Tianjin, the critical issue existing in groundwater corrosion evaluation has been solved through a research on environment type and drying wetting cycle effect referring to groundwater corrosion evaluation. The determination method of water level for prevention of up-floating under different circumstances has been drawn from the analysis of water level for prevention of up-floating.
