| Abstract: | According to the limited balance method of rigid body, the stability of Dayantang, Mayanwan and Taizishang landslides in head of Shuibuya hydropower station at the Qingjiang River, has been analyzed and calculated from the two aspects, i.e. susceptibility of influence factors and safety coefficients. The calculation of susceptibility is obtained by means of gaining the local derivatives of the safety factors to each influence factor. The calculation of the safety factors is used sarma method, jianbu method and push method respectively. In addition, the strength parameters of soils in the landslide zone are calculated with anti-evolutionary way. According to the conclusion of calculation, some constructive proposals about the landslide control are put forward. |
