摘要
结合广东某液化天然气工厂项目桩基工程实例,分析在土洞、溶洞等岩溶较发育-发育的不良地质条件下,冲孔灌注桩的施工特点;论述施工过程中如何采用填充碎石、粘土,钢护筒跟进及填充砂石、注浆等措施来处理岩溶区域溶洞层的施工技术.
Based on a case of a liquefied natural gas plant project in Guangdong province,this paper analyzes the construction features of grouted stake under unfavorable geological conditions,where soil cave is comparatively immature; Furthermore,this paper discusses how to employ the methods such as filling of stone,clay,steel casings,etc. to deal with the construction problems in cave floor in Karst area.
