摘要
在桥梁桩基施工中,会遇到多层孤石或溶洞及串珠状溶洞等复杂的地质情况,结合工程实例和工程地质状况,详细阐述了岩溶地质条件下桥梁桩基础钻孔灌注桩施工方案及施工技术,并就施工中容易发生事件与对不同厚度的溶洞处理技术方法进行了深入探讨。
In the construction of bridge pile foundation, there are complex geological conditions of multilayer boulder or karst cave and beaded karst cave. Combined with the engineering cases and engineering geology,the article sets forth the construction scheme and construction technology of cast-in-site pile for bridge pile foundation under the condition of karst geology in detail, and further discusses the incidents easily caused in the construction and the treatment technologies of the different thick karst caves.
