本文以海外项目老挝乌多姆塞省北本湄公河大桥为例,针对大桥南岸引道边坡护面墙滑塌进行现场调查及原因分析,经综合分析后提出防护优化设计方案,来提高路基边坡稳定性及边坡防护施工的可操作性,旨在防止今后出现类似的滑塌问题,以保证施工安全和项目的顺利进行。 Taking the North Mekong Bridge in Oudomxay, Laos, as an example, this paper conducts a field investigation and analysis on the slippery of the retaining wall on the south side of the approach bridge. After comprehensive analysis, it puts forward the optimal design of protection to improve the subgrade slope Stability and operability of the slope protection construction are designed to prevent similar slip problems in the future so as to ensure the construction safety and the smooth progress of the project.
