The Shantou city is located in the eastern part of the Guangdong province in China, 300 kilometres east of Hong Kong. The Shantou SuAi crossing consists out of two identical TBM made tunnels with a length of 3,500 km crossing the SuAi river. The crossing will connect Longhy district at the northern bank and Haojinag district at the southern bank. Both tubes have an outer diameter of 14.50 m and accommodate 3 traffic lanes.
The responsible design institute has performed the necessary analyses, but since the tunnels are located in an area with high seismic intensity and independent analysis by an international consultant was considered. For this, China Railway Tunnel Design Institute (CRTDI) has awarded TEC to execute an independent seismic analysis.
