铜川市新川滑坡破裂机制浅析

铜川新川滑坡是一典型的人为工程活动引起的地质事件。滑坡直接威胁着新川水泥厂的生产系统和一些主要辅助设施，它的孕育和发展成为该厂致命性的隐患。本文在全面调查和必要的探测基础上，根据滑坡的场地条件和破裂特征，用力学的观点对滑坡的破裂机制进行了分析。结果指出，导致坡体破裂的主要原因是坡体内部自重应力场变化的结果，并把破裂过程划分为三个阶段，为进行稳定性评价和治理设计提供了依据。

Fracture mechanism on xinchuan landslide of tongchuan city,shaanxi province

Xinchuan landslide in Tongchuan City, which is a typical geological event induced by artificial engineering activity, directly menaces the productive system and part of its supplementary facilities of Xinchuan Cement Plant. The generation and development of landslide will be a destructive hidden danger to this plant. On the basis of overall investigation and necessary probe, the landslide and its fracture mechanism are analysed with the point of view of mechanics in accordance with in situs condition and the fracture characteristic. The authors ascribe the failure of the scarp slope mainly to the change of self-gravity strain field, and suggest that the fracturing process may be divided into three stages so as to provide a basis for the stability assessment and administration project.
