| Abstract: | Zhenjiang is located in a hilly area in Jiangsu Province. In recent years, investigation data shows that short-term strong
rainfall or long-lasting rainfall in Zhenjiang area often induced a large number of shallow landslides. So, rainfall is the main influencing
factor of landslides in Zhenjiang area, which has caused great economic losses. In this paper, more than 300 mountain slopes in
Zhenjiang area were investigated in detail, and the relationships between landslides and rainfall related parameters were analysed
based on meteorological data. The relationships between rainfall, duration and the number of landslides were obtained. The I-D curve
of rainfall threshold in Zhenjiang area was determined, and the analysis results were compared with those in other areas. The research
results provided a basis for landslide control, early warning and prediction in Zhenjiang area. |
