中文摘要: 藏东南的喜马拉雅东构造结地区作为青藏高原隆升最快的地区之一,其复杂的地质背景条件决定了该区工程地质问题具有复杂性和特殊性,并孕育了多种地质灾害。利用测窗、节理裂隙分期配套等野外调查方法以及遥感影像解译,分析总结了藏东南地区鲁朗至通麦不同区段崩塌滑坡地质灾害的孕灾地质背景,据此将研究区划分为四段,分别为鲁朗-东久段、东久-拉月段、拉月-排龙段、排龙-通麦段,每一区段分别对应了不同的孕灾地质条件特征,由此也决定了区段内崩滑地质灾害的性质、变形破坏模式、规模。相关成果可用于藏东南崩塌滑坡地质灾害的早期识别和风险评价。
Abstract:Eastern Himalayan Syntaxis, as one of the fastest uplifting region in Tibetan Plateau, its complex geological environment determines that the engineering geological problems have complexity and particularity and give birth to a variety of geo-hazards. Based on the survey results of the project "Geo-hazards investigation in main towns and major highways in SE Tibet", the geological conditions of landslides along Lulang-Tongmai were analyzed. According to the analysis, the study area could be divided into four sections, respectively, which are Lulang-Dongjiu section, Dongjiu-Layue section, Layue-Pailong section, Pailong-Tongmai section. Each section corresponds to different disaster-inducing geological conditions, which determines the nature, deformation and failure mode and scale of landslide in the section. The conclusion could be used in risk assessment and early identification of landslides in SE Tibet.
