摘要
在《岩溶发育地区桩基特性模拟研究》项目成果模式的指导下,对溶洞顶板较薄的地层采用了人工挖孔桩+旋喷+钢管桩的复合桩基加固方式,详细介绍了复合桩基设计方案的优选过程及其承载力计算。实践证明,该设计方案对类似工程具有一定借鉴作用。
Guided with the result of ＂Study on Simulation of the character of pile foundation in a karst area＂, a cave roof with thin stratum method was reinforced with compound pile foundation （cast-in-situ pile by hand excavation ＋ spiral jet ＋ steel pipe pile）. The whole optimization process of the compound pile foundation design program and the calculation of its bearing capacity have been introduced in details. Practice has proved that this design program can be used for reference in the future.
