某滑坡稳定性分析评价

Stability Analysis of a Landslide

通过现场勘察并在分析该滑坡特征及成因等的基础上,利用传递系数法和推力法简化方程式计算滑坡的稳定性。结果表明该滑坡近期在雨季处于不稳定状态,旱季表层土体处于欠稳定状态,而地震时处于不稳定状态。根据稳定分析及推力计算,滑坡区为整体滑移区,在确保治理工程的经济合理性和安全性的前提下,采取防治措施,防止其再次扩大范围,减少损失,确保居民安全。

Based on the field investigation and analysis of the characteristics and origin of the landslide, the stability of the landslide is calculated by using the transfer coefficient method and the simplified method of thrust. The results show that the landslide area is unstable in the rainy season, the surface soil in the dry season is in an unstable state, and the earthquake is in an unstable state. According to the stability analysis and thrust calculation, the landslide area is the whole slip zone. Under the premise of ensuring the economic rationality and safety of the control project, the prevention and control measures should be taken to prevent it from expanding again, reducing the loss and ensuring the safety of the residents.
