摘要
论述了承压水对高层建筑基坑支护、桩基础、抗浮锚杆(桩)施工的不利影响。结合工程实例,介绍了喷射注浆止水墙处理承压水的设计方法,并分析了总施工顺序、涌水钻孔处理和地下水水位观测等关键技术问题。
The unfavorable effects of confined water were discussed briefly on the construction of foundation pit support, pile foundation and anti-float anchor （pile） for high-rise building. Combined with a engineering project, the design method of jet grouting cut-off wall in confined aquifer was elaborated. Key techniques, such as general construction sequence, treatment of gushing water in prospect hole and ground water--level observation, were also analysed in this Paper.
