  • Water resistance is one of the most important factors which affect the speed of the fording landslide when it enters water at a high speed. The experiment system is designed. It includes movement apparatus, sensor apparatus, speed control apparatus and transmission apparatus. Six blocks with different areas of water attaining surface are selected to carry out experiments. Each block moves in water at five different speeds. They are 0.5ms-1、0.8ms-1、1.0ms-1、1.5ms-1 and 1.8ms-1. The correlation between Incremental pressure head and moving speed is analyzed by experiment method. The pressure head model is established to the resistance of water attaining surface when blokes move in water. As for the curved-surface sliding model of fording landslide, the forces of sliding masses both in water and above water are calculated. The kinetics equation and kinematics equation are used to calculate landslide speeds. At last, the speed model of fording landslide is put forward by slice method when landslide moves along a curved slip surface. The paper takes the Dayantang landslide that was located on the north side of Qing River and occurred on June 15, 2007 as an example. The speeds of landslide with water resistance acting on water attaining surface are compared with those of landslide without water resistance. The influences on the landslide speed from the water resistance are quantitatively analyzed.
