摘要
由于公路沥青路面设计规范提供的回弹模量值的公式是建立在弹性半空间理论基础上,与实际的情况有一定的出入,故在考虑标准车后轴两侧车轮荷载对贝克曼梁测定值影响的基础上,推导出修正的弯沉与回弹模量理论公式,并以工程实例验证其适用性,具有一定的现实意义。
In the specification for design of highway asphalt pavement, putting forward the formula of calculating rebound module for subgrade based on the theory of elastic half space, and there are some differences from practice. The amendatory formula about deflection and rebound module is worked out aften considering the force from all the wheels and the formula is tested by practice, which has much practical means.
