摘要
我国一些地区地下岩溶(溶洞)流塑特别发育,甚至出现多层溶洞,地下地基的不确定因素较多。通过工程实例,归纳了复杂岩溶地区桩基设计的要点、溶洞的处理方法,以及桩基施工要点,通过现场桩基测试,检测桩身质量及提供桩承载力特征值。
The quantities of karst topography appear in some zones of our country, such as complex karst holes, multi-layers hole and some other uncertain factors. Through the case, the points of pile design in the complex karst zone, treatments for karst holes and points of pile construction were generalized in this paper ,the pile length and pile capacity can satisfy the requirement of pile design by the test of piles.
