Guangzhou–Shenzhen–Hong Kong Passenger Line Shiziyang Tunnel

Description

The Shiziyang tunnel on the Guangzhou-Shenzhen-Hong Kong passenger line is located between Dongyong station and Humen station. Soil conditions (clay and sand) are too poor to ensure that the tunnel has stable foundations for its intended lifetime. A dynamic analysis of the Shiziyang tunnel determined that vibration mitigation measures were necessary.

Solution

The CRTSI isolated slab consists of a prefabricated track slab on a track mat (t=27 mm). The height adjustment was carried out by CA mortar between the track mat and the first concrete. The stiffness of the mats was adjusted in three steps, ensuring a smooth transition from the CRTSI isolated slab track to the standard slab track.
