摘要
选择3个不同剖面,对上三公路5#滑坡稳定性进行分析。结果表明:在厚度大的松散堆积土层路基中,第四系松散堆积物与基岩风化带接触部位往往会成为斜坡破坏的潜在滑动面;降雨将使边坡稳定系数降低。根据分析结果,提出了对不稳定地段预应力锚索加固治理方案。
With three different profiles,stability of 5# landslide of Shangsan highway is analyzed.The result reveals that the contact part between quaternary loose accumulative formation and weathered zone of bedrock often becomes the potential sliding surface in road bed of thick loose soils,and rainfall will reduce the stability factor.And treatment schemes of prestressed anchor cables are proposed for unstable sections.
