摘要
基于车辆动荷载的特点以及国内车辆普遍超载的实际情况,将车辆动荷载等效简化为集中静荷载。应用Boussinesq解和分层总和法,以4个工程实例分析了车辆动荷载的影响深度以及路堤高度和车辆超载程度2个重要因素对影响深度的影响。分析结果表明,不超载情况下,车辆动荷载的影响深度大约在6.0～8.0m范围内,超载情况下,其影响深度大约在6.0～14.0m范围内;车辆动荷载的影响深度随路堤高度的降低而呈线性关系增大,随车辆超载倍数的增加而呈抛物线关系增大。
Considering the characteristic of vehicle loads and the actuality of overloading of vehicle in China, simplifying vehicle loads as equivalent static concentrated load, using Boussinesq solution and layer-wise summation method, the influential depth of vehicle loads and its two important influencing factors, embankment height and overloading degree, were analyzed performed on four actual examples. Results indicate that the influential depth of vehicle loads is about 6.0-14.0 m in the condition of overloading...
