Mechanical behaviour of a sprayed concrete lining isolated ...

01/03/2015  The mechanical behaviour of a SCL with a sprayed waterproofing membrane was examined. ... Laboratory tests were conducted to examine the mechanical behaviour of a sprayed concrete lining isolated by a sprayed waterproofing membrane. The loading applied to these tests was designed to simulate the predominant loading conditions expected in the vicinity of a tunnel junction.

MODERN COMPOSITE SPRAYED CONCRETE WATERPROOF

In these case studies the composite sprayed concrete waterproof lining with spray applied membrane was applied as the functional waterproofing and support of the tunnel. The design of the tunnel linings comprise both drained and undrained structures. Experiences with design, construction and cost-effectiveness are compared and discussed.

DESIGN OF SPRAYED CONCRETE FOR UNDERGROUND SUPPORT

SPRAYED CONCRETE Depending on the mechanical properties of the ground, and on the dimension and depth of the opening, sprayed concrete can serve one of the following purposes (Heuer, 1974): • (1) For lightly fractured grounds, of high strength in comparison to the natural stresses they are subject to before excava-tion, the role will be that of a simple “pro-tective skin”,thus preventing ...

12/05/2020  Sprayed concrete linings (SCLs) used in tunnels generally develop secondary deformations over time, even in the presence of constant stress levels within the lining. These deformations influence the loading process on the lining and therefore also the stress levels within the support structure. The behaviour of a SCL in a tunnel was investigated under different operating
