真空预压法在滨海港软基中的应用研究

Study on the Application of Vacuum Preloading Method in Soft Foundation of Binhai Port

依据滨海港工业园区站的地质情况和工程特点,针对吹填土和软土地基的加固处理,通过分析比较三种加固方案的优缺点;选择真空预压法进行现场试验,跟踪监测其沉降量、孔隙水压力、水平位移变化,并进行了综合分析。结果表明:真空预压对场地软土地基的加固效果较好,可为类似工程的研究提供参考。

According to the geological conditions and engineering characteristics of Binhai Port Industrial Park,aiming at the reinforcement treatment of dredger fill and soft soil foundation, through analysis and comparison the advantages and disadvantages of three kinds of reinforcement plans, the vacuum preloading method has been selected for field test, and the settlement, pore water pressure and horizontal displacement change have been monitored and comprehensively analyzed as well. The results show that vacuum preloading has better reinforcement effect on soft soil foundation which can provide reference for the research of similar projects.
