边坡灾害风险评估系统研究及应用
摘要
风险评估是降低边坡灾害损失的有效途径.论文以地理信息系统GIS(Arcview)为基础进行二次开发
建立边坡风险评估系统.通过该系统建立边坡的三维地质模型
根据模型的物理力学参数等属性数据
运用Monte-Carlo法计算三维边坡的失效概率
分析经济风险和生命风险
最后给出定量的评价.实例分析结果表明
该系统在经济与生命风险评估方面可为相关决策提供依据.
Abstract
Landslides caused substantial damage to property
which is seriously hampering social development.With the use of geographic information systems(Arcview)
a risk assessment system is established in the paper.The failure probability of 3D-slope is calculated using the Monte Carlo method.The risk of life and economic losses were also calculated by the risk assessment system.By a case study
the results of the risk of life and economic losses may be crucial foundations for administrant branch.
