本文采用解析法、三维有限元法和物理模型试验方法对某一无梁岔管进行了结构分析。分析结果表明，钢衬钢筋混凝土无梁岔管与无梁明钢岔管相比，具有受力条件好、钢衬较薄、施工方便、安全性高、造价低等优点，是一种新的岔管结构形式，具有广阔的应用前景。

本文在综合分析坝内埋管现行设计理论和方法的基础上，提出了坝内埋管极限状态设计方法。该方法以钢筋混凝土非线性分析为主要手段，可以同时考虑坝体荷载、内水压力、温度荷载的作用，全面分析坝内埋管中钢管、钢筋和混凝土的应力状态和承载情况，并决定钢管壁厚和外围坝体混凝土的配筋，它对于改进坝内埋管的强度设计，具有重要实际意义。

Structural research into the performance of a composite steel-reinforced concrete penstock designed for use at the Three Gorges power station in China is described. The stress state, load capacity and mechanism of deformation of the penstock under internal water pressure were obtained from theoretical analyses based on a non-linear finite element simulation of the original design. Using the results from the numerical research, a large-scale prototype model has been developed and tested to verify the modified penstock. The conclusions obtained have potential value with respect to other similar projects both in China and elsewhere.

A composite stucture for penstock bifurcations, comprising a steel lining and outer reinforced concrete shell, is proposed as a method to increase structural integrity and reliability as a result of the interaction of the two materials. This method represents an economical solution for developing countries. Model studies for the concept are described.

论述了水电站课程多媒体教学软件的设计思想、制作方法和功能。软件内容包括：绪论、水力机械、水电站输水系统、水电站厂房、思考题和试题库五部分。软件用于水电站课程的课堂教学或课外自学，有效解决了《水电站》课程学时少、内容多的矛盾。提高了教学效果和学生的学习兴趣与积极性，可代替部分实习内容。
