Abstract 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.

Key words： rock and soil mechanics landslide stability analysis pipe network seepage reinforcement
