蒲江县寿安街道龙泉村滑坡特征研究
|
Abstract:
2020年8月18日，四川省成都市蒲江县寿安街道龙泉村发生多处山体滑坡。点多面广的滑坡摧毁2座高压铁塔，毁坏高压线路，导致乡村公路隆起、开裂，损毁沟渠、斜坡，造成一定的经济财产损失。综合运用无人机航测、现场地质调查等技术手段，初步揭示滑坡的破坏特征、基本特征和形成原因，分析了滑坡的形成条件和诱发因素。目的是揭示红层地区浅表层滑坡的发生规律。成果有助于高压铁塔及线路故障应急处置，指导高压线路勘察及设计，并对丘陵和山区工程建设避让地质灾害危险区和影响区提供参考。
Extensive landslide happened in Longquan village, Shou’an town, Pujiang county, Chengdu city, Sichuan province on August 18, 2020. The rock mass destroyed 2 high-voltage towers and 1 high tension line, caused arching and cracking of county road, damaged ditches and slopes, resulting in certain economic property loss. Through UAV aerial photography and geological survey, this paper discovers destroyed feature and deformation cause of the landslide, analyses its deformation condition and inducing factor. The purpose is to announce the occurrence regularity of the surface and shallow landslide in red layer area. The achievement helps emergency disposal of high-voltage tower and line fault. It can be used to guide prospecting and design of high-voltage line. Reference measures can be taken for projects in mountainous areas to avoid dangerous areas and affected areas of geological hazard.
