真空预压排水固结法在工程中的设计实践

Design Practice of Vacuum Preloading Drainage Consolidation Method in Engineering

结合广州南沙某污水处理厂工程实例,介绍了真空预压排水固结法软基处理的设计。根据工程南北分区实施过程中的沉降实测数据,分析了真空预压下地基竖向沉降计算中经验系数的取值,并反算得到该工程淤泥层的沉降经验系数,可为今后类似工程选择地基处理方案提供借鉴和参考。

Combined with a sewage treatment plant in Nansha,Guangzhou,the design of soft foundation treatment by vacuum preloading drainage consolidation method was introduced.According to the measured data of settlement during the implementation of the north and south partition,the value of the empirical coefficient in the calculation of the vertical settlement of the foundation under vacuum preloading was analyzed,and the silt layer’s empirical coefficient of the project was calculated reversely,which can provide reference for similar projects in the future to select the foundation treatment scheme.
