بيت /tunnel lining design with staad
The shape and size of lining are defined by size, depth and function of the tunnel and sort of take up load (rock pressure, hydrostatical pressure, traffic load, etc). Castinplace lining is mainly used for construction of tunnels with most complex structure and big crosssection.

What is this PAS about? Segmental tunnel linings are currently designed with reference to a large number of standards and documents. This PAS brings all of these together into a single, usable standardization document that aims to reduce unnecessary administration and delay by streamlining, clarifying and standardizing the design process for segmental lining design.

A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal.
