钢筋应力释放法中开槽参数对钢筋应力的影响研究

Research on Influences of Slotting Parameters in Reinforcement Stress Releasing Method on Steel Reinforcement Stress

以一块10 m长的简支预应力空心板桥为例,通过有限元计算和分析,研究钢筋应力释放法中混凝土开槽的长度、宽度和深度等参数对普通钢筋应力的影响,以便更为精准地研究钢筋应力释放法的测试精度。

Based on a 10m long simply-support pre-stressed hollow slab bridge as an example,this paper studies influences on parameters such as concrete slotting length,width and depth,etc.in reinforcement stress releasing method on stress of common reinforcement for more accurate research on test precision of reinforcement stress releasing method.
