Abstract:
To determine the reasonable burial depth range for the Qinwang Crossing Project's river-crossing section in the Fuchun River, a mathematical model was first employed to simulate the planar water level distribution and flow field condition of the river segment. Based on these simulations, physical model tests were conducted to study the maximum scour depth at the tunnel site under four combined flood-tide scenarios(Scenarios 1-4): upstream boundary with 100-year flood discharge + downstream boundary with 100-year flood water level, upstream boundary with 100-year flood discharge + downstream boundary with lowest tidal water level, upstream boundary with 300-year flood discharge + downstream boundary with 100-year flood water level, and upstream boundary with 300-year flood discharge + downstream boundary with lowest tidal water level, results were cross-validated with mathematical model calculations for accuracy. The research results indicate that under the same flood discharge, when the downstream tide is low, the river flow is greater, the water level is lower, and there is a significant difference in water levels between upstream and downstream. Consequently, the flow velocity is relatively high, making erosion more likely in the river channel. For Scenarios 2 and 4, by calculated the mathematical model the maximum scour depths of 4.50 and 6.45 m, respectively, by yielded while the live-bed scour model the maximum scour depths of 1.50,1.95, 2.40, and 4.50 m under the four scenarios respectively. The live-bed scour tests reflect the riverbed scour conditions during the corresponding flood duration(70 hours in prototype)and under the extreme hydrological conditions, with scour depths aligning well with actual conditions, providing valuable references for safety control in shield tunneling river-crossing projects.8 tabs, 9 figs, 25 refs.
