| 摘 要： | 根据基坑开挖的特点,改进常规三轴试验仪器的控制程序。以此为基础,利用三轴仪对基坑开挖过程中土体的侧向卸荷过程进行模拟,获取土体变形参数,并对某工程实例进行有限元分析。分析结果表明,经过侧向卸荷三轴试验获得的土体变形参数的计算结果与实测数据更吻合。

| Abstract: | Following the characteristics of foundation pit excavation,the triaxial apparatus control procedure was changed and the soil lateral unloading was simulated just like foundation pit excavation.Taking a project as an example and doing finite element analysis by using unloading indexes,the analytic results which use unloading indexes agree well with the measure data. |

| Keywords: | triaxial test lateral unloading stress path deformation |
