AbstractConstruction solid waste (CSW) landslides are always characterized by high mobility, and thus pose much danger to surrounding residents and buildings. In this study, a back in situ analysis of the catastrophic CSW landslide occurred in Shenzhen in December 2015 is presented, in which the motion-accumulation evolution process of the landslide and damage to structures are reproduced, and reasonable agreement between the simulation and actual conditions is obtained. In landslide process modeling, a depth-averaged model that can undergo dilation and contraction during deformation is adopted to simulate the behavior of the landslide assuming different conditions of initial solid volume fraction. The results show that a small initial solid volume fraction of a water-laden landslide undergoes small resistance caused by dilatancy. On the basis of landslide process analysis, the fluid-solid interaction is decoupled and considered to be a one-way action of the landslide on structures, which is reflected in the form of impact force. Structural response is evaluated by 3D finite element modeling. The failure process presents a type of plastic hinge formation at the beam-column connection positions, followed by local destruction of the impacted columns, and final structural failure is the cumulative result of this damage over time. This integrated approach could be implemented in quantitative risk assessment procedures pertaining to landslides.
