cast-in-place items; limited accessibility (i.e. due to liners or other components); severe functioning environmental conditions, and inaccessibility to RCS parts. Furthermore, both the effects of ageing and the qualitative nature of many non-destructive evaluation Structural Design Considerations Introduction With the exception of larger bridges, most highway structures designed for a 50 to year service life often begin to reach their practical service life at about 30 years of age. Though this is commonly a result of increases in traffic or higher safety standards, the

The tunnel has a total length of 5, m, including two sections excavated with a TBM and one with drill-and-blast, as shown in Fig. the east side of the Wuyuanwan station, a shaft is constructed to connect the TBM and the drill-and-blast Final cast-in-place liner being installed within an initial, gasketed, pre-cast, concrete segmental liner.

The tunnel, located in heavily weathered rock up to ft below the I Beltway around Washington, DC, was constructed by drilling through the rock and constructing a cast-in-place concrete liner.
When the main riser of the new tunnel failed during initial the interpretation of the results of site and laboratory tests with respect to the tunnelling process, soil and rock classification, etc., • Information on line, cross-section, drainage, and structural elements affecting later use of the tunnel.
Tunnelling and Underground Space Technology, Vol. 3, No. Alternatively, structural loads can be transferred to stronger competent strata at depth by the use of - Bored piles - Diaphragm wall elements - Mixed in place (MIP) piles - Piles reinforced by steel bars - Vibrated concrete columns.
Technical literature on all these special alternative construction techniques is available on request from Alternatives study. At the outset of preliminary design, an alternatives study was completed to determine the preferred method for replacement. The possible methods investigated included open cut replacement, installation of a new transmission watermain in tunnel and structural rehabilitation of the existing pipes using the Cured in Place Pipe (CIPP) Watermain :// “Cast-In-Place Concrete”.
Submit the following test reports: a. Compression tests on cylinders for grout topping and fillet grout, as specified in Section “Concrete Tests”.
Compression tests, on mortar cubes for non-shrink grout and for tunnel liner and pipe grout, as specified in Section The second structural problem involving multiple cracks is the fracture test of a real-size concrete lining specimen of a waterway tunnel, as shown in Figure (Abo et al., ).The test was carried out to investigate the cracking behavior and fracture process of a tunnel lining with void formation above the ceiling area and uniformly distributed loads applied to the sidewalls and to study Book series: Structures and Infrastructures.
