山区高速公路弃渣场工程的安全关乎路域范围内环境保护、水土保持、公路建筑物及下游环境敏感点等的保护,提出安全评估方法十分必要.该文基于云南省内1 369座弃渣场资料分析,提出弃渣场工程安全风险影响因素,概括为选址和设计因素、施工因素、区域地质因素、外部影响因素及资料完整性因素共5个一级指标,进一步提出18个次级指标.建立群决策AHP模型,通过64名技术专家,确定次级指标的权重,构建高速公路弃渣场工程安全风险评价技术指标体系,提出风险等级分级标准.以大理至丽江高速公路一处弃渣场实体工程为例,检验了弃渣场安全风险评估评价体系,证明了评价体系具有简单易行的优点,权重优化需要实践大数据的支撑,该评价体系适合在山区高速公路弃渣场工程中进行推广运用.
Study on Safety Risk Assessment System for Waste Dump of Mountainous Expressways
The safety of waste dump projects of mountainous expressways is related to environmental protection,water and soil conservation,highway building protection,and downstream environment-sensitive point protection,so it is necessary to put forward safety assessment methods.Based on the data analysis of 1 369 waste dumps in Yunnan Province,the safety risk factors of the waste dump engineering were proposed and summarized as five primary indicators,including site selection and design factors,construction factors,regional geological factors,external influencing factors,and data integrity factors,and 18 secondary indicators were further put forward.The group decision-making analytic hierarchy process(AHP)model was established,and the weight of secondary indexes was determined by 64 technical experts.The technical index system of safety risk assessment of the expressway waste dump engineering was constructed,and the risk classification standard was set.With a waste dump engineering of Dali—Lijiang Expressway as an example,the safety risk assessment system of the waste dump was tested,which proved that the assessment system was simple and easy to implement.The weight optimization needs the support of big data in practice,and the assessment system is suitable for promotion and application in the waste dump engineering of mountainous expressways.
