摘要
以连云港某港中心货运站地基加固工程为例,结合海相软土场地预压实测数据,分析探讨了真空堆载联合预压效果。结果表明:海相软土预压后的物理力学指标获得较好改善,排水板深度范围内的土层得到不同程度的压缩变形,土体抗剪强度增幅普遍在200%~300%之间,这说明海相软土场地采用真空堆载联合预压处理是可行的,可供类似工程设计施工借鉴。
Taking the foundation reinforcement project of a port central freight station in Lianyungang as an example,and combined with the measured preloading data on the marine soft soil site,the paper analyzed and discussed the effect of vacuum surcharge preloading.The results show that the physical and mechanical indexes have improved,the soil layer in the depth range of drainage plate is compressed and deformed,and the increase of shear strength of soil is generally between 200%and 300%,which proves feasible and provides references for design and construction of similar projects.
