水泥路面接缝位移研究

On Joint Displacement of Cement Concrete Pavement

本文采用位移交分原理，求得了水泥路面接缝不同约束时的位移公式，并得到了填料为Ｂｕｒｇｅｒｓ体时的位移解．计算表明，约束条件及缝宽对接缝位移有较大影响，必须结合施工条件由计算确定缝宽．本文结果也可供桥面及其它种类路面接缝的设计和施工时参考．

With the help of displacement calculus of variations,the joint displacement formula for bath elastic and Burger's materials are obtained under different constraint conditions.The result shows that jointdisplacement is greatly affected by constraint conditions and joint width.Thus,the determination ofjoint width should be calculated by jointly considering the joint construction conditions.The results ofthis paper are of referential values for joint design and construction of both bridge deck and other kindsof pavement.
