摘要

对于25m以下的路堤边坡,公路工程抗震设计规范规定了其在地震作用下边坡设计的综合地震影响系数的取值。针对目前公路路堤边坡不断增高的趋势,对25m以上的高路堤边坡进行地震作用下的稳定性分析,并对计算结果进行分析、汇总,探讨得出了高填土路堤边坡的地震动力放大系数公式。
For road dike lower than 20 meters, specifications of earthquake resistant design for highway engineering rules its value of influence coefficient under earthquake function. Aiming at the trend which the highway road dike increase more and more high, this paper analyze the seismic response for side slope stability of road dike higher than 20 meters and analyze the calculation result. The conculusion will be the basis of the side slope design under earthquake function. This coefficient will be write in specifications of earthquake resistant design for highway engineering rules and uses in engineering design.
