摘要
结合武黄城际铁路湖北地区岩溶发育地质条件,对桥梁钻孔桩施工过程中的溶洞处理进行了论述,溶洞处理采用了预注浆和回填造壁法施工,确保了工程质量,缩短了钻孔桩施工工期。
After the discussion on the handling method of the Karst cave in the process of the bored pile construction,the cave treatment adopted the technique of the advance grouting and backfilling wall-building to assure the project quality and shorten the bored pile construction period whiling considering of the Karst geological development in Hubei province of the Wu-Huang inter-city railway.
