摘要
大灶火西南山蛇纹岩矿及透闪石玉矿采选项目临时用地(租赁)建设工程位于格尔木市郭勒木德镇,开展建设工程地质灾害危险性评估可为后期工程安全建设提供重要依据.评估结果表明,炸药库与 1#生活区内地质灾害类型为不稳定斜坡(Q)、泥石流(N).其中,不稳定斜坡(编号Q1、Q2)发育程度中等,危害程度中等,现状评估危险性中等.泥石流(N1)发育程度中等,危害程度中等,现状评估危险性中等.2#生活区内地质灾害类型为不稳定斜坡,不稳定斜坡(Q3)发育程度中等,危害程度中等,现状评估危险性中等.后期可采用合理排水、有效支护等措施,确保边坡稳定.
Abstract
The temporary land(lease)construction project for Dazaohuo Xinanshan serpentine rock ore and tremolite jade ore mining and selection projects is located in Golmud Town,Geermu City,and conducting a geological hazard risk assessment for the construction project can provide important basis for the later safety construction of the project.The evaluation results indicate that the geological hazards in the explosive storage and 1#living area are unstable slopes(Q)and debris flows(N).Among them,the unstable slopes(numbered Q1 and Q2)have a moderate degree of development,moderate degree of harm,and moderate risk in the current assessment.The development level of debris flow(N1)is moderate,the degree of harm is moderate,and the current assessment of the danger is moderate.The geological hazard type in the 2#living area is unstable slope,with moderate development and harm level of unstable slope(Q3),and the current assessment shows moderate risk.Reasonable drainage and effective support measures can be adopted in the later stage to ensure the stability of the slope.
