高速公路桥墩处滑坡分析及治理方案研究

滑坡是山区道路桥梁工程常见的地质灾害,而滑坡体受自然和人为活动影响发生的蠕动变形将严重威胁到桥梁的结构安全和高速公路行车的安全。以安徽省某高速公路桥墩处滑坡为例,通过现场调查的研究手段,分析了滑坡的形成条件以及影响滑坡稳定性的主要因素。通过滑坡理论计算分析,论证了该滑坡的稳定性。根据滑坡的特点,提出"支挡防护+防排水"的综合治理措施,加固后坡体整体处于稳定状态,证明了加固方案取得了良好的工程效果。对类似滑坡工程治理有一定的参考价值。

Study on the Analysis and Treatment Scheme of Landslide at the Bridge Pier of Expressway

Landslide is a common geological disaster of road and bridge engineering in mountains areas, the creep deformation of landslide body affected by natural and man-made activities will seriously threaten the safety of bridge structure and expressway driving. This paper takes a landslide at the bridge pier of expressway in Anhui Province as an example, the formation conditions of the landslide and the main factors affecting the stability of the landslide are analyzed by means of field investigation. The stability of landslide is proved by theoretical calculation and analysis of landslide. According to the characteristics of the landslide, the comprehensive treatment measures of "support protection +waterproofing and drainage" are put forward, and the whole slope is in a stable state after reinforcement, which proves that the reinforcement scheme has achieved good engineering effect. It has certain reference value for similar landslide engineering treatment.
