摘要
福建省三明市图书馆工程地层地质条件比较复杂,岩溶洞穴发育不均衡、无规律。采用填充32.5R水泥、优质黏土、片石(体积比为3∶1∶1)的方法和灌砂压浆法、钢护筒法相结合的方法处理溶洞,通过桩基静载荷试验,验证了桩基承载力特征值满足设计要求,说明该工程所采用的溶洞处理的桩基施工技术是合理可行的。
The geological structure of the Fujian Sanming library was complex, and the karst cave devel- opment was unbalanced and irregular. The karst cave was treated with the method of the filling 32.5R ce- ment, high-quality clay, stone tablets （ volume ratio of 3 ： 1 ： 1 ）, fifiling sand and grouting, and steel casing. The pile bearing capacity has met the design requirements by pile static load test, which showed that the pile foundation construction technology of handing karst cave was reasonable and feasible.
