摘要
本文论述了马蹄湾滑坡地质灾害的孕育，发展（滑动）起动的地质和地貌条件；分析研究了灾害的特征和形成机理。指出，岩层的松动变形和在重力场作用下的蠕动变形不仅界限了滑坡的形态和规模，而且还决定了该滑坡灾害的特征和成因类型；指出该滑坡发生在碎裂岩斜坡，属性质特殊的复合型地质灾害。最后提出了整治与防范该滑坡灾害的工程措施建议。
In this paper, a comprehensive discussion about the geological and geomorphic conditions, and the mechanism of formation of Matiwan landslide has been made. It is pointed out that loosening deformation and creeping deformation of the rock mass forced by gravity load field control the shape and scale of the landslide and determine the characteristic and type of the slide-collapse disaster as well. The author point out that properties of Matiwan landslide is special, and it is a compound and disastrous natural slip-slacktip whose movement was quite slow and lasted for a long time. At last, author gives the engineering measure which renovate and project this landslide disaster.
