摘要
路基坍塌是秦岭山区公路的主要病害之一。以108国道K1561+250段路基沉陷为例,结合工程地质和水文地质条件对其形成的原因进行了分析,认为该段路基的沉陷与地下水和气候条件有密切关系。在考虑暴雨对坡体影响的基础上,对该坡体进行了稳定性计算评价。以此为依据,确定了锚固工程辅以排水的整治方案,并按工程要求进行了整治设计,经工程整治后检验,该方案起到了稳固坡体的作用。
The surface subsidence is one of the main roadbed diseases in Qinling Mountain. This paper takes the roadbed with surface subsidence as an example which lies in K1561 ＋250 of the national way 108 and analyzes the cause of formation based on the condition of engineering geology and hydrology geology. It is concluded that the main causes of surface subsidence are ground water and climatic conditions in the area. On the basis of the design is made good effect for stabilizing slope.
