Internal force analysis on steel concrete lattice by reverse beam method for landslide control

Lattice beam with anchor has been widely applied to landslide control since the technique is effective to prevent the deep and subsurface landslide failure,and prettify the environment.But design method is mainly based on experience,which may bring material waste and hidden trouble for the internal force analysis fault.The reverse beam method is discussed on internal force analysis on steel concrete lattice for landslide control in the paper.Following conditions are simplified:(1) the anchoring force is vertical with lattice beam and axis force is neglect.(2) the stiffness of longitude beam is greater than that of latitude,so the internal force analysis is based on exceeding static determinacy continuous beam.The method is applied to Xiufengsi landslide stabilization at the Three Gorges Reservoir.
