摘要
山区勘察应充分调查场地周边环境地质条件,对可能存在承压水的场地应进行分层止水观测地下水位。桩基施工中出现了涌水现现象应调查分析产生的原因,采取经济合理的处理措施。
Geotechnical investigations in the mountain terrains should thoroughly inspect the environmental geology conditions in surrounding areas.Layered groundwater observations might be necessary for areas that the artisan groundwater levels are suspected.As a case history,this paper presents that,in the cast-in-place concrete pile installation site,large quantities of groundwater were gushing into the boreholes.The groundwater gushing mechanism was investigated,and cost effective mitigation measures were provided.
