近年来我国不断承接国际水利水电工程总承包项目,但在实施过程中相对于国内工程,由于国情、技术规范和合同条款等方面的原因经常造成诸多设计上限制.巴基斯坦Daral Khwar水电站的非对称月牙肋钢岔管体型复杂,先采用结构力学按概率极限的原则对钢岔管进行初步设计,再用有限单元法复核其强度和刚度,经过完整严密的设计论证实现设计优化,最终得到咨询工程师和投资方的认可.为以后类似项目积累了经验,具有一定的实践意义.
In recent years, China has been continuously undertaking the EPC project of international water conservancy and hydropower projects, but many design limitations often result from its national conditions, technical specifications and contractual terms compared with domestic projects during its implementation. Asymmetrical crescent at Daral Khwar Hydropower Station in Pakistan The rib steel bifurcation body is complex, the first use of structural mechanics according to the principle of probability limit of the steel bifurcation pipe preliminary design, and then use the finite element method to review the strength and stiffness, through rigorous design and demonstration to achieve design optimization, and ultimately get consulting engineers and The approval of investors, which has accumulated experience for similar projects in the future, has certain practical significance.
