河龙水库电站建设用地地质灾害危险性评估

Risk Assessments on Geological Disasters of ConstructionLand of Helong Reservoir Hydropower Station

根据勘测成果、实际调查资料和遥感地质解译等,采用气象学、水文学、地质学、工程地质学、水文地质学、环境工程学、计算技术等多学科交叉的综合方法,通过对大量信息进行分析与处理,首次全面系统研究了工程区主要的环境地质条件、现状条件下存在的地质灾害和工程建设可能遭受地质灾害的危险性,工程建设可能诱发、加剧地质灾害的可能性,并进行地质灾害危险性综合评估,认为河龙水库电站遭受的地质灾害为崩塌和泥石流,危险性小。提出了对不稳定岩块予以撬除或锚固及冲沟种草植树的切实可行的防治措施。

A large amounts of information, obtained from the survey results, actual survey data, remote sensing geological interpretation and so on, has been analyzed and processed based on the integrated using of many subjects, involving meteorology, hydrology, geology, engineering geology, hydro-geology, environmental engineering and computational techniques, etc, which study related problems of the construction land in Helong Reservoir Hydropower Station, including its main environmental geological conditions, geological disasters existing in the current situation, risk of construction that may suffer from geological disasters, possibility of engineering may induce and aggravate the geological disasters, then the authors have assessed the risk of geological disasters comprehensively, and believe that the risk of geological disasters is small in Helong Reservoir Hydropower Station, only collapse and debris flow may happen here,it is feasible that prying or anchoring the unstable rocks, and planting trees and grass in gully can control them.
