| 中文摘要: |
| 湛江港某工程堆场地基土层是由新近人工回填的素填土和原始海相沉积淤泥、淤泥质土组成的深厚软土地基，素填土土质极不均匀，呈欠压实状。淤泥、淤泥质土层承载力低，含水量高，为高压缩性软弱土，地基处理均采用堆载预压。项目交工后对堆场的沉降进行长期沉降观测，观测数据显示4个堆场均出现不同程度的沉降。总结了堆场工后沉降的主要特点、规律，分析了造成沉降的主要影响因素。为减少堆场工后沉降和不均匀沉降，根据堆场的功能、面积、荷载、地质资料等，提出堆场运营管理、软基处理设计、排水设计等针对性处理措施，有效消除后期沉降对堆场正常生产运营的影响，旨在为类似工程的设计、管理提供参考。 |
| 英文摘要: |
| The foundation soil layer of a certain engineering stockyard in Zhanjiang Port is a deep soft soil foundation composed of recently manually backfilled plain fill soil and original marine sedimentary silt and muddy soil.The plain fill soil is extremely uneven and in an undercompacted state.The silt and muddy soil layers have low bearing capacity,high water content,and are high-pressure compressible soft soil.The foundation treatment adopts preloading.After the completion of the project,long-term settlement observation is conducted on the settlement of the stockyard.The observation data shows that the four stockyards all have different sizes of settlement.This article summarizes the main characteristics and laws of post construction settlement of the stockyard,and analyzes the main influencing factors that cause settlement.To reduce post construction settlement and uneven settlement of the stockyard,targeted treatment measures such as stockyard operation management,soft foundation treatment design,and drainage design are proposed based on the function,area,load,and geological data of the stockyard,which can effectively eliminate the impact of later settlement on the normal production and operation of the stockyard.The aim is to provide reference for the design and management of similar projects in the future. |
