摘　　要：依托珠海铁建广场项目开展现场试验,简要介绍此技术的施工工艺,对膜下真空度、表层沉降、分层沉降、孔隙水压力和温度计等进行了全程监测,确定该技术的加固效果并分析电渗板深度对软基加固效果的影响。研究结果表明:EKG电渗联合真空预压技术的加固效果优于真空预压法,在一定范围内,电渗板长度越大,EKG电渗联合真空预压技术对软土层的加固效果越好。Based on Zhuhai Railway Construction Square project,and the construction technology of this technology was briefly introduced.The whole process of monitoring such as vacuum degree under film,surface settlement,stratified settlement,pore water pressure and thermometer were carried out.The reinforcement effect of this technology is determined and the influence of the depth of electroosmotic plate on the reinforcement effect of soft foundation is analyzed.The results show that the reinforcement effect of EKG electroosmosis combined with vacuum preloading is better than that of vacuum preloading.In a certain range,the larger the length of electroosmotic plate,the better the reinforcement effect of EKG electroosmotic combined with vacuum precompression technology on soft soil layer.
