摘要
基于正交试验设计方法对高速公路软土路基沉降的离散元模拟数据进行极差分析,结果表明,各影响因素对高速公路软土路基沉降的敏感性大小依次为:软土厚度>路基坡度>地基承载力;并据此提出了高速公路软土路基沉降的控制措施。基于最小二乘法原理,建立了高速公路软土路基沉降的回归预测公式,定量描述了高速公路软土路基沉降与影响因素之间的关系。
Range analysis was used for analyzing the discrete element simulation settlement data of expressway soft soil roadbed based on orthogonal experimental design.The results demonstrate that the sensitivity of the size follows by：the thickness of the soft soilsubgrade slopebearing capacity of foundation soil.And accordingly,settlement control measures of expressway soft soil roadbed were brought forward.At last,with the least square method,regression forecasting model of expressway soft soil roadbed was established,which describes the relation between settlement of expressway soft soil roadbed and the influencing factors.
