水泥混凝土路面传力杆设计的力学分析

Mechanical Analysis on Dowel Design of Cement Concrete Pavement

基于Timoshenko弹性基础上的传力杆承担荷载变形和杆组变形的线性分布理论,分析传力杆直径、布置间距对承担荷载有效传力杆根数、接缝处传力杆的变形以及传力杆承受的剪力、弯矩与混凝土接触界面应力的影响,阐述传力杆间距、直径设计的思路和方法。

According to the deformation of bearing load of dowel and its linear distribution theory,it analyzes the influence of dowel diameter and layout spacing on effective roots number of dowels which bear load,the deformation of dowels at the joints,the bearing shear and moment of dowel,and stress at concrete contact interface.The design ideas and methods for the pitch and diameter of dowel are also described.
