针对甬台温高速公路某边坡在开挖过程中出现了局部失稳的情况,文章从工程地质、水文地质和稳定计算等方面对失稳的原因进行了分析,并提出了采用边坡锚索、钢筋混凝土格子梁结合地表与地下排水的综合处治措施。处治结果标明该措施达到了安全、稳定、经济的目的。
In view of the situation of partial instability during the excavation of a side slope of Ningbo-Taizhou-Wenzhou Expressway, the reasons of instability are analyzed from aspects of engineering geology, hydrogeology and stability calculation, and the application of slope anchor Cable, reinforced concrete lattice beam combination of surface and underground drainage of the comprehensive treatment measures. The result of the treatment shows that the measure has reached the goal of safety, stability and economy.
