摘要
以实际工程为例,概述了超长桩基在岩溶、土洞发育地区的施工难点,并针对施工难点提出了改进措施。详细介绍了岩溶、土洞的处理方法和桩基施工技术,实践结果表明,在岩溶地区桩基采用冲孔的办法进行处理,既满足质量要求,又可以缩短工期、降低成本。
Based on the engineering practice,this paper outlined the construction difficulties of super-long pile foundation in karst area and proposed improvement measures. The treatment methods of karst and soil cave were introduced in detail as well as the pile foundation construction technology. Engineering practice shows that the bored pile for treatment in karst area can meet the quality requirement, shorten the construction period and reduce the cost.
