Plastic drain board overload pre-pressure reinforcement in deep soft soil monitoring and analysis

以惠州大亚湾石化工业区D1地块软基处理工程为背景,结合工程的具体特点和工程地基沉降和稳定性要求,选用塑料排水板超载预压法对该软基进行处理.通过制定现场监测元件布设方案,进行动态监测加固地基的地表沉降、分层沉降、孔隙水压力和深层土体水平位移,使沉降变化规律很好地运用于施工控制.再结合现有理论研究成果,探讨塑料排水板超载预压法加固深厚软土的变形规律及加固效果,对塑料排水板超载预压加固深厚软土的相关参数进行研究,从而为工程的优化设计和施工安全提供科学依据,并为类似工程提供借鉴.

This article takes Huizhou Daya Bay Petrochemical Industrial Zone D1 plots soft ground treatment works in the background, combined with the specific characteristics of the project and meet the engineering foundation settlement and stability requirement, selection of pre-molded plastic drainage plate overload pressure method for processing the soft ground. Through the development on-site monitoring component layout scheme for dynamic monitoring of reinforced ground surface settlement, layered settlement, pore water pressure and the horizontal displacement of deep soil, so that a good settlement variation applied to construction control. And then combined with the existing theoretical research to explore plastic drain pre-loading method, overloading deep soft soil deformation and strengthening effect on the plastic drain overload, pre-loading deep soft soil parameters studied, so as to optimize the design of the project construction safety and provide a scientific basic,and provide reference for similar project.
