摘　　要：为了提高震区公路的抗震防灾能力,提出了考虑地震风险的高烈度地震区公路路线方案评价方法。从路线方案评价关键影响因素分析出发,建立了包含地震风险、经济、环境、安全的两层次路线方案评价指标体系;采用标度分值和专家打分相结合的方法,构建了评价因子的量化模型;确定了以多准则评价为基础的高烈度地震区路线方案评价方法,建立了基于方案达成度和综合度的交互式路线评价模型;最后以甘肃陇南某震区公路为实例,对评价方法进行了实例分析验证。研究结果表明:实例分析的路线A方案综合风险值为11.91,B方案为7.87;A方案安全指标为14.5,B方案为16;B方案经济指标和环境指标大于A方案;A方案的达成度为0.660,B方案的达成度为1.852,最优方案为B方案;给出的评价方法能有效量化地震风险对路线方案的影响,计算结果准确可行。In order to improve the seismic disaster prevention capability of road, the evaluation method of highway scheme in high seismic intensity region was proposed. With the analysis on key factors influencing the alignment selection, a two-level assessment system with seismic risk, economy, environment and safety as index was established. Using the method of scale scores and expert scores, the quantitative model of evaluation factors was established. Considering the environmental features in high seismic intensity region, evaluation method of highway scheme in high seismic intensity region based on multiple criteria evaluation was defined, and the interactive evaluation model of highway alignment based on alternative achievement and complexity degree was set up, and the method was verified by taking certain seismic road of Southern Gansu as instance. The results show that the comprehensive risk of route A is 11.91, and that of route B is 7.87. The security index of route A is 14.5, and that of route B is 16. The economic index and environmental index of route B are greater than those of route A, and the achievement degree of route A and route B are 0. 660, 1. 852 respectively, and the optimal solution is route B. The assessment methods effectively reflects seismic risk of highway scheme, and the assessment model is feasible. 4 tabs, 4 figs, 17 refs.
