摘要
通过坝内圆孔结构的模型试验,结合钢筋砼非线性有限元分析,探讨了圆孔结构在坝体荷裁作用下的受力特征和破坏形态,提出了圆孔结构的配筋计算方法,并提出用RCNL计算机程序进行大体积砼结构配筋计算的具体步骤。
Investigation is made into forced behavior and failure form of the circular hole structure under loading by means of model test and in combination of non-linear FEM analysis Of reinforced concrete. The calculation method of reinforcement is presented for the circular hole structure. The practical steps for calculating the reinforcement of great volume concrete structure conducted by the computer program《RCNL》 are also provided.
