水坝下游桥渡清水冲刷计算是个难题,我们籍助广泛的现场资料与两座桥的试验报告,提出了数学模拟法。利用线一座1964年洪水冲刷资料验证发明,结果满意。
The calculation of the water erosion at the lower reaches of the dam is a difficult problem. We applied the extensive field data and the test reports of the two bridges to propose the mathematical simulation method. Using a 1964 flood scouring data to verify the invention, the results were satisfactory.
