优化方法在削坡工程中的应用

Application of optimality method on slope cutting project

对滑裂面固定的边坡进行削坡时 ,关键在于何处削坡使得土方量最小且边坡具有预期的稳定程度。本文利用最优化方法 ,将最小的削坡土方量作为目标函数 ,将预期的边坡安全系数作为约束条件 ,把该问题等价于一个有约束的优化问题 ,可找出最优的削坡方案。

The key to the cutting method on a slope with a fixed slide surface is where to cut in order to obtain the minimum earthwork and make the slope reach an anticipated stability. By the optimality method in the paper, the minimum earthwork of slope cutting is regarded as target function, and the anticipated factor of safety of slope as a constraint condition, so this problem is equivalent to optimality one with constraint conditions. Thus the optimal scheme of slope cutting can be obtained.
