济南绕城高速公路滑坡综合治理设计方案研究

Research on comprehensive scheme of strengthening the landslide for the Jinan express loop highway

针对济南绕城高速公路南线某路段的滑坡治理工程,提出了混凝土横梁加预应力锚杆和抗滑钢管加锚杆两套加固案例。通过对两种方案的主要工程量和加固技术进行分析,认为采用抗滑钢管桩和预应力锚杆联合加固技术是经济可行的,能够保证路基边坡的稳定。

From the practical example,this paper introduces the different schemes of＂concrete transversal beam ＋ pre-stressed bolt＂and＂anti-slide steel pipe ＋ bolt＂for strengthening the landslide from the aspect of technical economy.The results show that the comprehensive scheme—＂anti-slide steel pipe ＋ bolt＂of strengthening the landslide is technically feasible,and can satisfy the stability of the landslide.
