摘要: 通过某工程实例，阐述了坡顶为石砌挡土墙，中部为永久边坡，底部为深基坑的混合高边坡的支护方法，计算时，应根据不同工况、采用不同参数，进行至基坑底的基坑支护计算和至地面（基坑回填后）的永久边坡支护计算，支护结构需满足临时边坡和永久边坡。

Abstract: Based on an engineering example, a supporting method for a mixed high slope, which has stone retaining wall on the top and permanent slope in the middle and deep excavation at the bottom, is indroduced. According to different working conditions and by using different parameters, calculations of excavation support at the pit bottom and permanent slope support on the ground (after the backfill of excavation) should be carricel out. Supporting structures should satisfy the requirements of both temporary and permanent slopes.
