摘要
通过对典型路面结构的分析,探讨层间接触条件对路面结构受力状态的影响。计算与分析显示:层间接触条件对路面结构受力有很大的影响,不同界面的接触条件对不同的力学指标有不同程度的影响;第一、二界面的接触条件对层底拉应力的影响较大,第一界面的接触条件对面层最大剪应力有着决定性影响,第三接触面影响土基顶面压应变。
It discusses the influence aroused by strength state of the pavement structure to the interlayer touch condition. Calculation and analysis shows： the interlayer touch condition can greatly affect the strength state of the road pavement, and touch condition of different interlayer has different influence degree to the strength of the pavement structure. The touch condition of the first and second interlayer have greater influence to the ten- sion stress of the bottom layer. The first interlayer has fatefully influence to the shear stress, While the touch condition of the third interlayer affects the compression strain of the top of ground.
