摘　　要：为解决广州市南沙某场地施工过程中软弱地基处理问题,采取掏孔释放内压力、砂桩排水增大有效应力的方法,随着固结度增大与土体强度增加,可抑制周边建筑物的拱抬以及消散后续施工产生的附加应力。通过测试孔隙水压力以及变形量,验证了该处治技术满足工程要求。In order to solve the problem of the soft foundation in the construction process of Guangzhou Nansha,it digs holes to release the pressure,and the sand piles drainage to increase the effective stress.With the degree of consolidation increased in soil strength,surrounding buildings arch lift has been inhibited and the additional stress has been generated by the subsequent construction dissipate.Pore water pressure and deformation testing are verified the treatment technique to meet the construction requirements.
