摘　　要：为了研究用高性能水泥复合砂浆钢筋网薄层(HPFL)加固RC双向简支板的抗弯性能,对同参数的1块对比板和4块HPFL加固板进行试验,并用有限元软件ANSYS进行模拟。试验研究与数值模拟结果均表明:与未加固板相比,加固板的抗弯承载力与刚度都有较大提高,加固后板的抗裂性能明显改善,从而验证了HPFL加固RC板能改善其抗弯性能。还采用塑性铰线理论对该类加固板的承载力进行了分析和计算,计算结果与试验结果及数值模拟结果相似程度较高。In order to study the flexural capacity of reinforced RC bidirectional simply supported slab of high-perfor-mance cement Ferro cement laminate （HPFL）, made experiments on 1 contrasting plate and 4 HPFL reinforcement plates with the same parameters, and simulated with ANASYS software. The experimental result and the simulated result both indicated that compared with the non reinforcement plate, the reinforcing plate flexural bearing capacity and stiffness were greatly improved, and crack resistance performance of reinforcement plate was obviously improved. It was confirmed that the HPF-reinforced RC plate was capable of improving the plate flexural performance. The plastic hinge line theory was adopted to analyze and calculate the bearing capacity of the reinforcement plates, and the calculating result was highly similar to the test and numerical simulation results.
