With the swift development of the hydroelectric project in our country, a set of large or extraordinary hydropower stations are being designed or constructed, such as the Three Gorges hydropower station, Longtan hydropower station, Xiangjiaba hydropower station, Xiaowan hydropower station, Pengshui hydropower station etc. All these hydropower stations adopt underground workshop, and have long diversion pipe system, and have one or two surge-chambers or adopt tailrace tunnel with sloping ceiling.

随着我国水电事业的迅速发展，一批大型、特大型水电站正在设计或处于待建之中，如三峡水电站、龙滩水电站、溪洛渡水电站、向家坝水电站、小湾水电站、乌江彭水水电站等，这些电站多采用地下厂房，具有较长的引水发电系统，并且设有调压室或采用变顶高尾水洞。

To all project practicality, the introduction is given to the operational characteristics, the methods for calculation and the researching actuality of the tail tunnels with sloping ceiling underground hydropower stations the Three Gorges. This paper has discussed in detail the characteristic method being the same with the compressive flow and the Priessmann solution being the same with the free-surface-pressure flow. And how to deal with boundary conditions has been expatiated. Also hydraulic transient process of tremendous load fluctuation in the tail tunnels with sloping ceiling has been numerical simulated and the Fortran program for numerical simulation has been given. The paper gain the maximal press for tail end of the shell, the maximal rising rate of rotational speed of generating set, the maximal vacuum degree for inlet of the tail tunnels and so on under 11 kinds conditions of tremendous load fluctuation. These conditions include the design conditions, the check conditions and the superposition conditions. Finally, the computing results have been analyzed and summarized. The end chapter is the general comment of the whole-length content and the describing of the intending view of researching.

本文以三峡右岸地下电站尾水洞设计为背景，从工程实际出发，阐述了变顶高尾水洞的工作特性、使用范围及其研究现状；详细论述了适用有压流的特征线法、适用明满交替流的普里斯曼解法等数学模型；边界条件的给定和明满交替流的计算方法；用Fonran语言编制了数值计算程序，对三峡右岸地下电站变顶高尾水洞的大波动工况进行了数值模拟，分别得出了在设计工况、校核工况和叠加工况下蜗壳末端最大压力上升值、机组最大转速上升值和尾水管进口最大真空度等重要参数；对数值计算结果进行了详细分析并得出了有价值的结论；最后展望了今后水电站变顶高尾水洞的研究方向。

Soaring from the top, it looked like a snap shot of the Three Gorges in China.

从上向下望去，好似见到了三峡的微缩景观。

The main reason that this bridge hasn't been built wildspread is lack of profound structural research and majorized design method. This paper connected with the project Kaziwan Bridge in the Three Gorges Reservoir Zigui County is on the base of the subject"the Research of Committed Technic about Prestressed Concrete Chord-Stayed Truss Bridge".The purpose of this paper is to research the static and dynamic characteristic under different loads,define the value of the design parameter and induce the structural characteristic and majorized design method through creating and analysing the spacy finite element model.

本文以实际工程三峡库区秭归县卡子湾大桥为背景，以湖北省交通厅科研立项课题"预应力混凝土斜拉桁架结构关键技术研究"为依托，通过建立分析空间有限元模型，旨在研究斜拉桁架桥在各种工况下的结构静、动力特性，确定设计中关键性参数的合理取值，并从以上分析研究中总结出斜拉桁架桥基本的结构特性与合理的设计方法。

Because the Three Gorges lie in dividing position between the upstream and midstream of the Yangtze River, and is located in the transition position between the second and the third relief stepladder, so the evolution research of the Yangtze River at this reach is more important and valuable.
