摘要:

采用抗滑桩、挡土板、预应力锚索、被动防护网、主动防护网、截（排）水渠、回填植树等工程措施对兰州市金城关徐家湾不稳定边坡进行综合治理，达到了安全效益、生态效益和经济效益的最优结合。在分析该区域工程地质条件的基础上，提出了设计总体思路和治理目的，重点介绍了各项工程措施的设计及施工要点。

Abstract:

For the comprehensive control of an unstable slope in Lanzhou, by the use of anti-slide pile, soil retaining plank, pre-stressed anchor cable, passive protection net, active protection net, cutting (drainage) channel and backfill planting, the optimal combination of safety benefit, ecological benefit and economic benefit were achieved. Based on the analysis on regional engineering geological conditions, the paper puts forward the overall design ideas and introduces the design of various engineering measures as well as the construction points.
