| 摘 要： | 结合三峡工程实际，对坝内埋管结构进行了非线性有限元分析，着重研究了不同管顶混凝土厚度和配筋对管道结构应力和强度的影响．计算结果表明，增大管顶混凝土厚度，可以明显提高坝内埋管的抗裂安全，确保混凝土大坝的整体稳定性，但是配筋多少对管周混凝土的抗裂能力影响较小．

| Abstract: | In combination with practice of the Three Gorges Project, nonlinear finite element analysis of the penstocks embedded in the dam has been carried out,in order to study the effects of the different thickness of concrete around the penstock and of the reinforcement in concrete on their stresses and strength. The calculation resalts show that the increasing the thickness of concrete around the penstocks can obviously improve their anti cracking safety and guarantee the stability of the concrete dam, but the reinforcement in surrounding concrete has less effect on its anti cracking ability. |
