摘要
从应力状态入手分析真空联合堆载加固软基的特点和机理，在此基础上建立在真空联合堆载条件下计算地基稳定性的数学模型，并提出抽真空作用下真空度衰减公式和土体抗剪强度增量的计算公式，并应用于某真空联合堆载试验段的稳定性分析中。
On the basis of effective stress principle, the characteristics and mechanism of improving soft foundation by vacuum－ pile preloading method are analyzed.A mathematical model is established for calculating stability of improved foundation.In addition, formulas are introduced to present the attenuation of vacuum pressure as well as the increase of soil’ s shear strength， which are applied for stability analysis of a certain vacuum preloading test section.
