摘要
为了在路线设计过程中提高高速公路的稳定性与承载度,研究全新的高速公路路线设计方案。以山东省任德高速公路为例,通过构建路线设计方案评估指标体系,如实反馈方案中每个环节的优劣;采用模糊综合评价方法与层次分析法相结合,形成路线设计方案评价模式,便于工程管理者选取合适的设计方案;依靠局部螺旋线集中升坡,避开隧道轴线与断裂带,完成高速公路路线的设计。测试结果表明:使用所设计的路线,地基累积的沉降量仅有50 mm,整体结构发生的水平位移平均为2.47 mm,说明所设计高速公路路线方案能够有效改善地基累积沉降的情况,同时也能够降低地基位移发生量。
In order to improve the stability and load capacity of expressway in the course of route design,this paper studies a new expressway route design scheme.Taking Rende Expressway in Shandong Province as an example,the evaluation index system of route design scheme is constructed to truthfully feedback the advantages and disadvantages of each link in the scheme.The evaluation model of route design scheme is formed by combining fuzzy comprehensive evaluation method with AHP,which is convenient for project managers to choose suitable design scheme.The highway route design is completed by focusing on the local spiral line and avoiding the tunnel axis and fracture zone.The test results show that:with the route designed in this scheme,the cumulative settlement of the foundation is only 50 mm,and the average horizontal displacement of the whole structure is 2.47 mm,which indicates that the highway route scheme designed can effectively improve the cumulative settlement of the foundation,and also reduce the amount of foundation displacement.
