直排式真空预压法加固吹填土地基的固结沉降分析
摘要:直排式真空预压法可以很好缩短工期、效果明显，是近年来在我国沿海地区广泛应用的软土地基处理方法。如何判别地基加固的程度，除了理论分析外，常常以地基处理过程中的沉降、孔隙水压力等指标的实时监测资料作为依据。以杭州湾地区吹填土加固工程为例，采用地表沉降和孔隙水压力的监测资料，分析加固地基固结沉降程度。结果表明，以沉降和孔隙水压力实时监测数据可准确判别吹填土地基固结程度，可为类似工程提供参考。

Abstract:The directly vacuum preloading method can shorten the construction period and has obvious effects.It is a soft ground treatment method widely used in coastal areas of China in recent years.In addition to theoretical analysis,realtime monitoring data of settlement,pore water pressure and other indicators are often used as the basis for judging the degree of foundation consolidation in the process of foundation treatment.In this paper,the consolidation degree of the foundation is analyzed by the project of blow-filled soil consolidation in hangzhou bay area.The result shows that the real-time monitoring data of subsidence and pore water pressure can be used to accurately determine the consolidation degree of the foundation,It can provide references for similar projects.
