陡峭的地形条件、软弱的岩土体组合、新构造运动条件是滑坡形成的基本条件,地震及极端季候条件是导致滑坡发生的直接诱发因素,而人类不合理的开挖、人工绿化灌溉、地震及持续降水则是今后滑坡体局部复活的重要因素.利用传递系数法,对滑坡体的稳定性进行验算,发现铁三小Ⅰ,Ⅱ,Ⅱ_1,Ⅲ号滑坡体在自然状态下均处于稳定—基本稳定状态,在地震及暴雨状态下处于基本稳定欠稳定状态.
Steep terrain conditions, weak rock mass assemblages and neotectonic movement conditions are the basic conditions for landslide formation. Earthquakes and extreme seasonal conditions are the direct triggering factors for landslide occurrence. However, human unreasonable excavation, artificial green irrigation, earthquakes And continuous precipitation is an important factor for the local revival of the landslide in the future.Using the transfer coefficient method, the stability of the landslide body is checked and it is found that the landslides Ⅰ, Ⅱ, Ⅱ_1 and Ⅲ are all stable in the natural state - The basic stable state, under the condition of earthquake and rainstorm, is basically stable and under-stable.
