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。

Abstract:  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.
