摘要
滑坡地质灾害是山区常见的灾害类型。在生态环境脆弱敏感的西藏山区,受控于复杂的地质环境、生态环境、人居环境等条件,滑坡灾害致灾能力极强,常造成难以估量的损失。西藏边坝县某滑坡变形特征显著,滑坡失稳将对滑坡区居民、建筑设施、公路及山区河道构成危害,查明该滑坡的特征是进行滑坡科学防灾减灾的基础。本文采用现场调查、工程地质测绘及钻探工程等多种研究手段,研究滑坡的基本特征,分析滑坡的影响因素,探讨滑坡形成机制及致灾效应,提出复杂山区人类工程活动开发与地质环境、生态环境保护相协调的建议。
Landslide geological disaster is a common type of disaster in mountainous areas.In Tibetan mountainous areas where the ecological environment is fragile and sensitive,controlled by complex geological environment,ecological environment,human settlements and other conditions,landslide disasters show strong disaster-causing capacity and often cause incalculable losses.The studied landslide in Bianba County,Tibet has significant deformation features,and the instability of the landslide will cause harm to residents,construction facilities,roads and mountain rivers in the landslide area.Finding out the features of landslides is the basis for scientific landslide disaster prevention and mitigation.This paper used field surveys,engineering geological surveying,drilling engineering and other research methods to study the basic features of landslides,analyzed the influencing factors of landslides,summarized the hazard effects of landslides,and put forward suggestions on coordinating the development of human engineering activities with geological environment and ecological environment protection in complex mountainous areas.
