通过２８根煤矸石砼拟简支梁抗剪强度试验，探讨剪跨比和配箍率对煤矸石砼拟简支梁抗剪性能的影响规律，并对试验结果与《轻骨料砼结构设计规程》中抗剪公式计算值进行对比分析．
Through the shear strength test of 28 simply supported beams with coal gangue, the influence rule of the shear ratio and the ratio of stirrups on the shear behavior of simulating simply supported beams of coal gangue are discussed. The experimental results and the structure design of lightweight aggregate are discussed. The comparative analysis of the calculated values of the shear formula in the Regulations.
