真空预压法作为一种有效的排水固结法软基处理手段,近年来在国内外的应用范围不断扩大。关于真空预压法的研究,在施工工艺、固结效果、计算方法等方面,已取得了大量的实验和实测资料,研究已日趋成熟,而在其微观加固机理以及三维分析方法等方面,笔者认为还有相当大的可探讨空间。本文以宁波大榭招商国际集装箱码头软基处理工程为研究对象,通过现场试验研究结合理论分析,对真空预压法加固沿海软土地基的微观机理进行初步探讨,期望能为该技术更深层次的研究砌筑台阶,并能为今后类似工程的软基处理提供参考与借鉴。
As an effective method of soft foundation treatment of drainage consolidation, vacuum preloading method has been expanding in recent years at home and abroad. As to the research of vacuum preloading method, a great deal of experimental and measured data have been obtained in the aspects of construction technology, consolidation effect and calculation method, and the research has matured. However, in terms of its microscopic reinforcement mechanism and three-dimensional analysis method, Think there is a considerable space to explore. In this paper, Ningbo Daxie China Merchants International Container Terminal Soft Foundation Treatment Engineering as the research object, through field experimental research combined with theoretical analysis of the vacuum preloading method to strengthen the microscopic mechanism of coastal soft soil foundation for the preliminary look forward to the technology for a deeper level Research masonry steps, and can provide reference and reference for soft foundation treatment of similar projects in the future.
