Rock-soil aggregate landslides are distributed all over the world and have done great harm to transportation networks, buildings, personal safety, and city construction. Although landslide studies usually focus on the slope of the single homogeneous material, few slopes are composed of or covered by various complicated geomaterials. This paper proposes a calculation model of the slope covered by rock-soil aggregate and analyzes Longhuguan landslide in Guangxi, China, considering rainfall. Fully considering the weak surface, a support design plan is given.The unbonded cable is taken to support the landslide, the concrete beams are adopted on the angle turning point of the surface, and the slide-resistant piles are used to jointly support the front edge of the slope. Top fissures are blocked and landslide drainage measures are taken. The displacement monitoring proves that the support is effective. This study can provide many references for landslide support and analysis covered by rock-soil aggregate.
