    • A system forming a tunnel beneath a railway (1) comprises a tunnel member (3) a platform member (2) eight support members (4), a slide member (5) for the tunnel member (3), and two slide members (6) for the platform member (2). In use, the tunnel member (3) is constructed in-situ adjacent to one side of the railway (1) resting upon the tunnel slide member (5), and the platform member (2) is constructed in-situ adjacent to the opposite side of the railway (1) resting upon the pair of platform slide members (6). A section of the railway (1) is then removed and part of the ground that was beneath the removed section of the railway (1) is excavated. The platform member (2) is pushed along the platform slide members (6) until the platform member (2) is resting upon the eight support members (4), and the removed section of the railway (1) is then replaced. The ground beneath the railway (1) and the platform member (2) is then excavated, and the tunnel member (3) is pushed along the tunnel slide member (5) until the tunnel member (3) is under the railway (1). The tunnel slide member (5) and the platform slide members (6) are then removed. In this manner the tunnel is formed beneath the railway (1).

    • The invention relates to an elongated housing (1) intended to withstand an internal pressure which may exceed 10 bars and forming a tubular sealed space (A) having a truncated cross-section, comprising a lower portion formed of a rigid concrete slab (2) resting on the ground and an upper portion (3) consisting of a thin metal wall shaped like a curved vault extending between two side extremities (31, 31') parallel to the longitudinal axis and each connected to the slab (2) by means of a longitudinal connection part connected tangentially to the side extremity (31, 31') of the vault (3). According to the invention, the upper face (22) of the slab (2) has a width substantially equal to the spacing between the two side extremities (31, 31') of the curved vault (3) and each connection part is comprised of a flat plate (4, 4') which extends in the prolongation of the vault (3) and is applied from the outside against the corresponding side face (23, 23') of the slab (2), each plate (4,4') being associated with support means (5, 42) capable of opposing the slipping of said plate (4, 4') along the corresponding side face (23, 23') of the slab (2) caused by forces (15) due to internal pressure and to the separation of said plates (4, 4') as a result of external forces (13).

    • An earth overfilled arched structure (10) includes a shallow arch (12) spanning a clear space. The sides of the clear space are formed by curved or straight walls. Solidified zones of earth material against the springs of the arch and/or behind the walls form foundation blocks which are in intimate contact via arch footings with the springs of the arch and/or with the upper part of the sidewalls in such a way that the arched structure delivers most or all of its support forces into the foundation blocks. Also, an overfilled arch bridge system includes a composite arch which has a precast layer and a cast-in-place layer. The system further includes means for reducing bending moments within the overfilled arch. The means include customizing the arch end geometry and prestressing the arch prior to or during loading. Precast arch elements which are formed and shipped in a use orientation. The precast arch elements can include arch footings and the system can include a plurality of precast arch elements. The arch elements can also be prestressed.
