结合浙江省舟山市金塘岛某工程,介绍了在大面积集装箱堆场地基处理中堆载预压法的应用和主要设计方案,并对该工程实施过程中的地基土的地面沉降、分层沉降、深层水平位移、孔隙水压力等监测项目及现场十字板剪切试验、标准贯入试验及室内土工试验等检测项目进行了详细的分析,并根据监测及检测结果对地基处理加固进行了效果评价,总结了该项目在堆载预压施工中的经验,提出了类似项目在堆载预压实施过程中应予以注意的问题。
Combined with a project of Jintang Island, Zhoushan City, Zhejiang Province, the application and main design scheme of preloading method for foundation treatment of large area container yard are introduced. The land subsidence and stratification of foundation soil during the project implementation are described Subsidence, deep horizontal displacement, pore water pressure and other monitoring items and on-site cross-plate shear test, standard penetration test and indoor geotechnical test items such as a detailed analysis of the project, and based on monitoring and testing results of the reinforcement of the foundation treatment effect The paper summarizes the experience of this project in the process of heap preloading, and puts forward some issues that should be paid attention to in the process of heap preloading.
