Pressure Tunnel and Shafts is a heritage-listed water supply system at Potts Hill, City of Canterbury-Bankstown, New South Wales, Australia. It was designed by the Water Board, …

The areas have been determined using tunnel pressure calculations made using the AEROTUN/4 one-dimensional characteristics program, an earlier version of THERMOTUN (ThermoTun …

用于水电站的有压引水隧洞的洞内流速应较泄水隧洞低得多，以减小水头损失，常按某一经济流速选择洞径。 有压隧洞的衬砌结构多种多样，应视岩石情况和水流条件选用，内水压力是衬砌 …

Pressure Tunnel (LTPT). The LTPT is a closed-loop wind tunnel that can operate at pressures up to 10 atm, thereby providing the capability to test at variable Reynolds numbers without …

1993年1月1日 · Pressure tunnels and shafts are excavated conduits, which convey fluids, most often water, under pressure. They can be either unlined, concrete lined, steel lined, or …

1994年10月1日 · This paper presents a framework to identify and evaluate the variables that control tunnel behavior and thus determine the key decisions made in the design of a pressure …

2018年10月1日 · Pressure tunnels are conduits which convey fluids, most often water under pressure. They are either permeable (unlined, shotcrete lined, concrete lined, reinforced …

The paper focuses on two pressure tunnels in the design of “Kąty-Myscowa” water reservoir. One of them serves as a discharge conduit, whereas the other plays an energetic role. Their

controlling tunnel behavior, as well as the sensitivity of the tunnel behavior to improvements in one or several of these key variables. This paper presents a framework for evaluation of the …

ing new design procedures for pervious pressure tunnels. Fractures and pores, which cause the mass, are deformed by the forces. rock mass around the pressure tunnel will be. internal...
