摘要
受多个断裂构造及其活动的影响,昆明地区喀斯特岩溶地基的水文地质情况极为复杂,导致区域内此类场地上高层建筑桩基设计和施工具有很大的难度.结合工程案例和实践经验,探讨类似地基上的工程地质勘察和与桩基设计施工相关的地下水影响及其控制、桩端嵌岩深度、孔底沉渣厚度控制等问题,并提出具体方法措施.
Controlled by many fracture structures and their activities, the hydro-geological conditions of karst foundation in Kunming are very complex, which leads to many difficulties in the design and construction of the pile foundation of high rise buildings in such an area. According to the engineering cases and practical experience, engineering geological prospecting, problems about groundwater impact assessment, rock socket-ed depth, control of the thickness of sediment and etc. were discussed, and some specific methods, measures and key points were put forward.
