| 摘 要： | 进行了真空联合堆载加固地基的稳定性分析,提出采用总应力法时,需考虑土体等向固结产生的土体强度增长和整体向心吸力的影响,用摩尔应力圆阐述了土体受等向固结应力和K0固结应力的不同特点,从而导出二者土体抗剪强度增长偏差的解析解,指出向心吸力的影响可建立模型用积分运算求得。

| Abstract: | It is necessary to consider the influence of the two factors when we use total stress method to analyze stability of preloading method combining vacuum with stack-load.The different between consolidation pressure K0 and he isotropic consolidation pressure will be expounded by Mohr's stress circle in the paper and we can get the fomula from it.The influence of stress toward center will be calculated by putting forword the calculating model. |

| Keywords: | vacuum preloading stability total stress analysis the isotropic consolidation pressure shear strength |
