Method for determining average distance between transverse cracks of continuous reinforced concrete
The invention discloses a method for determining the average distance between transverse cracks of continuous reinforced concrete. The average distance between the transverse cracks of the continuous reinforced concrete is calculated and determined through the following calculation formula: # imgabs0 # imgabs1 #. According to the method, the independent variable is the steel bar rigidity contribution degree # imgabs2 # concrete temperature shrinkage stress coefficient lambda c; according to the method, the average spacing of the transverse cracks can be efficiently and accurately determined, the phenomena that the result obtained by tedious table look-up of urban road specifications is inaccurate, and the pavement slab is broken and damaged due to over-conservative calculation of the road specifications are avoided, and great practicability is provided for engineering technicians.
本发明公开了一种连续配筋混凝土横向裂缝平均间距确定方法，所述连续配筋混凝土横向裂缝平均间距是通过如下计算公式计算确定的：#imgabs0##imgabs1#本发明建立了自变量为钢筋刚度贡献度#imgabs2#混凝土温缩应力系数λc，因变量为横向裂缝平均间距Ld的计算公式，本发明能够高效准确的确定横向裂缝平均间距，避免了城镇道路规范繁琐查表得到结果不准确，公路规范过于保守计算导致的路面板冲断破坏现象，为工程技术人员提供极大的实用性。
