地质勘察具有多方面的重要意义,地质勘察在工程项目设计与建筑施工中具有基础性的重要作用,在地质勘察中需要查明与岩土工程有关的水文地质问题,评估地下水对岩土体和建筑物的作用及其影响,同时也要提出预防及治理措施,以消除或减少地下水对岩土工程的危害。文章主要介绍了地质勘察的意义和其存在的问题,并提出地下水位升降变化引起的岩土工程危害,分析了岩土工程勘察中地下水问题,并提出了相关的解决措施。
Geological prospecting has many important meanings. Geological prospecting plays a fundamental and important role in engineering design and construction. It is necessary to identify hydrogeological problems related to geotechnical engineering in geologic prospecting, and to evaluate the effect of groundwater on rock and soil mass and The role of buildings and their impact, but also to put forward prevention and control measures to eliminate or reduce the groundwater damage to geotechnical engineering. This paper introduces the significance of geological survey and its existing problems, and puts forward the geotechnical hazards caused by the change of groundwater level. The groundwater problems in geotechnical investigation are analyzed, and the corresponding solutions are put forward.
