Numerical Simulation of Maximum Scour Depth of the Riverbed above a Subway Tunnel Crossing the Tidal River
To ensure the secure buried depth of the subway tunnel which was routed underneath the Fenghuahe River, a two-dimensional tidal current and sediment transportation model was established to simulate the maximum scour depth of the riverbed. The conclusions were shown as follows: the most disadvantageous hydrologic condition was a combination of the 200-year return period flood in the Fenghuahe River and the 5-year highest tide in the Yonghe River. The maximum scour depth of the riverbed above the subway tunnel was 1.19 m and the lowest elevation of the riverbed cross-section was -8.56m. The results could provide technical support for the safety of subway design.
