- Abstract:
- The geohazards are well developed in Guantang town of Guang’an district, Sichuan province. The main geohazards are avalanches, landslide and latent instability slopes. In the area the space distribution of the geohazards is obviously inhomogeneous, which affected by land form. Land form in this area is mainly composed of medium hill. The Mesozoic redbeds are widely distributed in the region, and the lithological features are hard sandstone interbedded with soft mudstone, whose attitude is approximate horizontal. Commonly there are huge thick sandstone layers on summit, vertical and large-spacing interval cracks are developed in the sandstone layer. Qujiang river and its tributary strongly cut the land form in this area, and forming special slopes, i. e hard sandstone with steep slope on the top and soft mudstone with gentle slope underlying, non-uniform rainfall and human activities are two main reasons leading to the development of geohazards.
