摘要
结合工程实际,重点介绍溶洞灌浆、旋喷桩和钢管桩在工程实例中的运用。实践证明,针对建筑场地的不同地质情况,采用溶洞灌浆、旋喷桩和钢管桩进行地基处理均是可行的。溶洞灌浆和旋喷桩对多溶洞地基处理效果明显,而钢管桩适用于基岩岩溶强烈发育(特别是多层溶洞)的地基处理。
Based on a foundation treatment project, karst cave grouting, jet grouting pile and steel pipe pile as well as their applications in actual engineering project were presented. The practice has proven that it is feasible to treat foundation by adopting karst cave grouting, jet grouting pile and steel pipe pile according to different geologic conditions, in which karst cave grouting and jet grouting pile are effective for foundation treatment in multi - karst cave area, and steel pipe pile in highly karstified bedrock areas （especially in muhilayercaves）.
