| 摘 要： | 首先利用拉格朗日有限差分法计算得到边坡开挖后的应力应变状态,然后通过滑面应力分析边坡的整体稳定状态,不仅可得到传统的稳定安全系数,而且可得到边坡的变形与受力特征.针对大连某高边坡工程实例,通过极限平衡法与数值分析法,分别得到原始自然边坡、开挖无支护边坡、预应力锚索加固边坡的整体稳定安全系数.工程实践证明,采用有限差分法...

| Abstract: | Based on the Fast Lagrangian Analysis Method,the stress-strain transfer mechanism of the excavated slope is obtained.Then,the excavated slope’s integral stability is calculated by the slip surface stress analysis method.And the safety coefficient and deformation are obtained.By comparison of limit equilibrium method and the slip surface stress analysis based on the Fast Lagrangian Analysis Method,the high slope engineering projects can be reinforced and supported by the prestressed anchor.The process of this new analysis method can be easy to use in practical high slope engineering projects. |
