西藏昌都白格滑坡斜坡地质结构特征及成因机制

混杂岩作为一种形成于板块俯冲和碰撞边界的特殊地质体，是由成分、时代、来源不同的岩块混杂堆积组成，岩体具有结构复杂、空间变化快、易蚀变、力学性质差异大等特点，在我国青藏高原地区广泛分布。受青藏高原复杂地质环境影响，混杂岩带往往是地质灾害频发带，对人类的生命财产和工程建设产生了巨大影响。基于此，本文对混杂岩的成因机制和地质特征进行了分析研究，阐述了青藏高原混杂岩带分布、地质特征以及混杂岩带典型地质灾害发育情况。在此基础上，对青藏高原混杂岩带地质灾害研究中存在的问题提出了研究方向，其研究结果可为青藏高原混杂岩带地质灾害研究提供参考。

Geological structure characteristics and genetic mechanism of Baige landslide slope in Changdu,Tibet

Melange is a special geological body composed of mixed accumulation of rock blocks with different compositions, ages and sources, which is formed at the boundary of plate subduction and collision. The rock mass has the characteristics of complex structure, rapid spatial change, easy alteration and large differences in mechanical properties. It is widely distributed in the Qinghai-Tibet Plateau of China. Due to the complex geological environment of the Qinghai-Tibet Plateau, the melange belt is often prone to geological disasters, which has a great impact on human life and property and engineering construction. Therefore, this paper analyzes the genetic mechanism and geological characteristics of the melange, and summarizes the distribution, geological characteristics and typical geological disasters of the melange belt in the Qinghai-Tibet Plateau. On this basis, the research direction of the problems existing in the study of geological hazards in the melange belt of the Qinghai-Tibet Plateau is put forward. The research results can provide a reference for the study of geological hazards in the melange belt of the Qinghai-Tibet Plateau.
