摘要
以新建杭州至长沙铁路客运专线(江西段)HKJX-3标段进贤特大桥施工为例,详细统计了溶岩发育程度,根据对桩基础施工中溶洞处理实际情况的记录,进行了溶岩地区钻孔桩施工溶洞大小、处理方案分析,进而提出了溶洞处理的措施与方法,缩短了施工工期,节约了施工成本,可为类似溶岩发育地区的施工提供借鉴。
Based on the construction of Jinxian Bridge inHKJX-3 section of New Hangzhou-Changsha Railway Passenger Dedicated Line(Jiangxi Section)as an example,this paper makes a detailed statistics of the development of karst rocks.Based on the record of the actual treatment of karst caves in the construction of pile foundation,it analyzes the size and treatment scheme of karst caves in the construction of bored piles in karst rock areas,then puts forward the measures and methods of karst cave treatment,which shortens the construction period and saves the construction cost,which can provide reference for the construction of similar karst development area.
