摘要
位于山东泰安市境内的205国道高峪铺公路-铁路立交桥,其接线挡土墙坐落在一非稳定边坡上,坡脚紧挨一条铁路干线。由于受路面汽车和坡下火车双震动源的影响,边坡连同挡土墙发生整体滑移,公路半幅交通被迫中断并严重威胁着坡下铁路的运行安全。针对这一工程灾害特例,从理论和实践两方面展开了深入研究,最终采取了合理的加固措施并取得了理想的加固效果。
In Taian City of Shandong Province, the retaining wall of Gaoyupu Cross Bridge on No. 205 National Highway is located on an unstable slope subjected to double dynamic loading, one is the vehicles running on the highway on the top of the slope, and the other is the train trucks acting on the bottom of the slope. On this condition, the whole slope and retaining wall lose their stability, which threatens the railway, and half range of the road was interrupted. According to characteristic of this engineering disaster, it is deeply studied the mechanism of the retaining wall instability and its reinforcing scheme, and good effect are obtained.
