摘　　要：本文通过９根钢筋砼开洞连续深梁在集中荷载作用下的试验，分析了其受力特性及影响抗剪承载力的主要因素，提出了抗剪承载力及斜截面抗裂计算的实用表达式，计算结果与试验结果符合良好。通过非线性有限元分析，比较了开洞连续深梁和不开洞连续深梁支座反力的异同点，给出了开洞连续深梁设计剪力（支座反力）Ｖ的计算方法。In this paper, based on the experimental results of 9 reinforcedconcrete deep beams with openings under concentrated loads, theload bearing characteristics and the principal factors affecting theshear capacity of the beams have been analyzed. The practical formulas for predicting the shear capacity and cracking strength ofthe inclined cross section are presented, and the calculated resultsshow a good agreement with the test results. By the analysis ofnon--linear finite element, the identical and different points betweencontinuous deep beams with openings and those without openingare compared, and the method for calculating the design shear VAof continuous deep beams with openings is put forward.
