Direct left turn from driveways is considered as a contributor to accident and delay in at-grade intersections. Safety benefits of prohibiting direct left turn from driveways have been identified in many studies. Several engineering alternatives have been developed to accommodate prohibited driveway left turns. These alternatives are (1) right-turn followed by U-turn at the down stream intersection;(2) right-turn followed by median U-turn before the intersection;(3) right-turn followed by median U-turn after the intersection;(4) upstream Jug Handle, and (5) downstream Jug Handle.

鉴于直接左转机动车交通常是路口事故和延误的诱因之一，左转禁驶在许多研究中都作为一项安全措施处理，直接左转处理方式有多种，大致包括：(1)下游路口右转后U形调头直行；(2)当前路口右转后在下一路口前的隔离带打U形调头直行；(3)当前路口右转后在下一路口后的隔离带打U形调头直行；(4)在当前路口上游打&壶柄状&转行；(5)在当前路口下游打&壶柄状&转行。

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.
