摘要
结合209国道恩施州龙凤坝至谭家坝段改建工程,经方案比选采用CFG桩复合地基对挡墙基础进行加固,并从组织试桩施工、桩基质量检测等方面进行了论述,各类试桩试验结果均表明CFG桩复合地基可充分保证基础的稳定性,满足设计要求,是一种适用于软土地基处理的工法。
Combined with the reconstruction project of Longfengba to Tanjiaba in China National Highway 209,the CFG pile composite foundation is adopted to reinforce the retaining wall foundation after scheme comparison.And the trial pile construction organization and pile quality detection are discussed.All kinds of test results show that CFG pile composite foundation can fully ensure the stability of foundation and meet the design requirements,which is a construction method suitable for soft foundation treatment.
