摘　　要：以某大型泵站电机大梁补强加固为例,介绍了采用在梁底及梁柱节点粘贴钢板的加固方法,以控制梁裂缝的开展并提高其承载能力,分析了梁加固后的受力状况,给出了加固后的承载力计算公式.计算结果表明,该方法能有效地提高梁的抗弯强度、梁端的抗剪强度及其承载能力,为有效解决同类工程实际问题提供了一种新的方法.Based on the engineering practice of strengthening concrete beams of large-scale pumping station, the method of sticking steel plates along the bottom of beam and the joint of beam-column is described and adopted so as to restrict crack development and increase bearing capacity. The behaviors of strengthened beam are analyzed and the formulas of bearing capacity for strengthened beam are presented. The calculation results show that the flexural strength shearing strength and bearing capacity of the beam is improved effectively and it offers the scientific ways for solving the practical problem in the similar projects.
