| 摘 要： | 根据预应力锚索地梁加固边坡工程的特点，对预应力锚索地梁的不同工作阶段和受力状态进行了详细分析，在此基础上提出了一种锚索地梁的极限状态设计方法，给出了其具体计算过程。应用该方法对某工程实例进行了计算，计算结果的对比分析表明，当锚索进入极限工作状态时对地梁进行极限状态的设计是必要的。

| Abstract: | According to the characteristic of the foundation beam with prestressed anchor-cable reinforcing slopes, a detailed analysis is carried out for different working stages and loading status of the foundation beam; and on the basis of it, a method for computing the limit state of foundation beam, is suggested;and the concretely computing process is given. An engineering case is calculated using the method; and the comparison shows that it is necessary to calculate the limit state of the foundation beam for designing when the anchor-cable is in the limit state. |
