【 摘 要 】

The concentrated precipitation has a great influence on the stability and deformation rate of the landslide in rainy season. The conventional methods often take the variation curves of total landslide deformation displacement, rate, and the anti-slide construction deformation or stress as indicators to evaluate the effect of the landslide control. But the precipitations are different in each year, which may affect the accuracy of the evaluation. Therefore, a reasonable indicator which is not dependent on the precipitation have to put forward. Based on the statistics of precipitation and deformation rate of Jinpingzi landslide in Wudongde hydropower station, the relationship between them has been concluded. And the precipitation influence factor of each year has been calculated and compared separately to evaluate the landslide control effect of Jinpingzi zone II. It is a new method which can be applied in hazard forecast based on weather forecast. The research results have important reference value for the same type landslides in this area.
