CRCP新型端部锚固制动板位移状态影响因素

The Factors Affecting of the State about the CRCP New Anchorage Displacement Brake Plate

连续配筋混凝土路面在季节性温度变化下将产生周期性变形,在板中由于受到土体约束而无位移,但CRCP的两端在一定长度范围内将会产生位移,这种位移量有时高达10cm。如此大的位移量必须采取一定的措施加以限制,以避免混凝土板被挤压破坏产生结构性失稳,提高连续配筋砼路面的稳定性,延长其使用寿命。

Continuously reinforced concrete pavement （hereinafter referred to CRCP） in the seasonal tem： perature changes will have a periodic deformation in the plate without constraints due to the displacement of soil, but the two ends of CRCP within a certain length will have a displacement, which Species displacement sometimes as high as 10cm or so. Such a large displacement of certain measures must be taken to be limited to avoid damage to concrete slab being squeezed a structural instability, improve the stability, widen the using age.
