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。

The hydraulic active vibration isolation technique attracts much attention recent years. In 1991, TOYOTA developed an active hydro-pneumatic suspension system for the SOARER car, which was composed of the pressure proportional valve and the hyaro-pneumatic cylinder. Comparing with the conventional passive suspensions, this system can provide a better ride comfort and handling.

计算机控制的液压主动隔振系统是国外近年来研究和应用较多的一种隔振系统。90年代初，日本丰田汽车公司在其部分高级轿车上安装了一种由压力比例阀和油气缸组成的液压主动悬架系统，与传统的被动悬架相比，该系统能更有效地隔绝路面不规则对车体的扰动和减小转弯、刹车等情况下车体姿势的变化。
