堆载预压法加固软基施工监测及效果评价

Construction Effect Evaluation and Monitoring of Soft Foundation Preloading Treatment

以中山市某码头项目软基施工监测项目为例,介绍了软土地基在堆载预压处理过程中其沉降和应力的变化规律。通过对软基处理施工过程中地表沉降、深层水平位移及孔隙水压力的现场监测及地基处理前后土体参数的检测,分析了软土地基的加固过程及加固效果。研究结果表明,堆载预压法处理码头陆域软基效果明显,能达到预期的加固目的。

Taking one dock project soft foundation monitoring construction in Zhongshan city as an example,this paper introduces the soft soil base settlement and stress change rules in the stack preloading treatment process.Based on the soft foundation treatment in the process of construction,deep horizontal displacement of ground surface settlement and pore water pressure monitoring and foundation soil＇s,it analysed the process and effect of the soft soil foundation reinforcement.Research results show that,preloading treatment effect of soft land base dock is clear and can reach the expected purpose of reinforcement.
