真空预压法加固软土地基机理相关问题的探讨

Problem on Mechanism of Vacuum Preloading Method in Soft Clay Foundation Consolidation

分析了真空度传递特性和影响因素,对涉及真空预压软土地基加固机理的相关热点问题进行了深入探讨,包括真空预压加固过程土体强度变化特征,加固区地下水位变化及有效加固深度,加固区边界的土体变形特征、边界水位变化及边界影响范围等,以助于更好地理解真空预压软土地基加固的机理问题。

The transfer characteristic and the influence factor of vacuum degree are analyzed, and a deep discussion on some disputed problems of mechanism of vacuum preloading method in soft clay foundation consolidation is given, including the soil strength variety characteristic, the underground water level variety in consolidation area and consolidating depth, the soil transmutation characteristic of consolidation area boundary, the boundary water level variety and the boundary influence scope, etc. so as to help to understand some problems on the mechanism of vacuum preloading method in the soft clay foundation consolidation.
