摘　　要：确定荷载设计标准是道路工程设计的前提,目前我国道路上行驶的重载车辆很多,相关道路设计规范虽已认识到重载车辆对道路的破坏性,但并没有就道路结构的设计具体规定重载车辆的最低限值。另因道路路面结构层的存在,路面结构层当量路基厚度的计入,减小了车轮荷载在路基中的工作深度,特别是对低填方路基,可使地基表层处理深度大大减小。Setting load design criteria-is the precondition of road designing. For various reasons, there are too many heavily loaded vehicles on the road in our country, which results in the destruction of roads. However, no specific regulation of the lower limit value can be found in any code of road design. On the other hand, if pavement structure layer is considered to be a part of the thickness, the working depth of load on the subgrade will be lessened, especially to the lower filled subgrade layer of subsoil. , which can greatly reduce the processing depth of surface
