Abstract

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.
- disaster-inducing geological conditions,
- landslide,
- eastern Himalayan syntaxis,
- SE Tibet
