The Pearl river estuary tunnel project of the ShenzhenJiangmen
railway is challenging. Many control factors along the route, including dense
ports and wharves, crossing multiple highgrade channels,
variable depths of river bed water, complex geological conditions, large scale,
and high risk, restrict the project implementation. To determine the route
scheme of the Pearl river estuary tunnel of the ShenzhenJiangmen railway, scheme research is conducted. First, the control
factors for the route selection, such as urban planning, waterways,
environmentally sensitive points, and geology on both sides of the Pearl river
estuary, are analyzed, and the appropriate locations of the crossing points are
selected. Second, two route schemes, the northern route scheme of ShenzhenHumenNansha crossing the river at the
estuary of the Taiping waterway in Human and the southern route scheme of
ShenzhenNansha crossing the river 500-m north of the
runway of Shenzhen Bao′an airport, are proposed.
Finally, based on the comprehensive comparison and selection of economic bases
in series, line conditions, construction difficulty of subsea tunnels,
operating conditions, impact on urban planning and environment, construction
period, and project investment, etc., the northern route scheme has more
advantages; hence, it is the recommended scheme.
