摘要
结合大连港大窑湾吹填区软土地基处理具体工程,通过现场试验与监测比较详细地介绍了堆载预压方法中关于分级堆载设计、施工及监测等各方面的技术问题。通过对监测结果的综合分析,探讨了堆载预压处理过程中地表沉降、深层沉降等关键参数的变化规律及堆载级数、堆载高度与固结时间等参数之间的依赖关系,为吹填造陆地区软基处理提供了经验和依据。
A case study of applying the preloading technique to treat hydraulic reclamation of Dayaowan Port area of Dalian is reported. The technical problems related to the stepped loading design, construction and monitoring are discussed. Through the analysis on the monitored data, variations of ground settlement and deep settlement with time are displayed and the interrelation among the step of preloading, the height of preloading and consolidation time are examined.
