摘　　要：应用微平面理论分析了素混凝土梁的承载力。首先,总结了微平面理论基本公式。然后将微平面理论与有限单元法相结合,分析了在外荷载作用下素混凝土梁的开裂全过程。通过与文献中的试验数据比较,验证了数值方法的有效性。The bearing capacity of concrete beam by micro-plane theory was analyzes.The basic formulae of the micro-plane theory were summarized,and the complete cracking process of concrete beam under the exterior load was described by combining the micro-plane theory with the finite element method.The experimental results demonstrated that the proposed method in this paper is highly feasible.

关 键 词：混凝土 微平面理论 有限元 承载力
