基于监测检测数据的真空联合堆载预压软基加固效果分析

Analysis of the Effect for Vacuum Combined Preloading on Soft Foundation Reinforcement Based on Monitoring and Detection Data

以深圳市大空港片区大面积软基处理为例,通过直排式真空联合堆载预压法处理软基的检测及监测数据分析评价地基处理效果,结果表明,采用直排式真空联合堆载预压法处理软基后软土的物理力学性质指标、十字板剪切强度均有提升,地表沉降合理、孔隙水压力逐步消散,平板载荷实验结果满足设计要求。

Taking an examplethe aslarge cale soft soil foundation treatment of the Shenzhen Dakong Port area.Useing the detection date and monitoring data analysis of the soft soil foundation treatment effect.The results indicate that direct vacuum preloading method can effective reinforcementsoft the soil foundation,In this process the physical and mechanical property indicators of soil and cross plate shear strength of soil would been improved.The pore water pressure gradually dissipates and the surface subsidence would reasonable.The results of the plate load experiment also meet the design requirements.
