通过实验室大型水槽内的模型试验和理论分析，对高速铁路长江沉管隧道基槽开挖过程中长江水流输砂量的变化以及泥砂冲淤对环境的影响作了研究，研究结果为高速铁路长江沉管隧道的初步设计提供依据
Through the model test and theoretical analysis in a large-scale laboratory tank, the change of sediment discharge in the Yangtze River during excavation of the Yangtze River immersed tunnel of high-speed railway and the impact of sediment deposition on the environment were studied. The results are as follows: high-speed railway The basis of preliminary design of Yangtze River immersed tunnel
