从分析实测的粘性土桥墩局部冲刷深度资料及遵循因次和谐的原则出发,得出了粘性土桥墩局部冲刷计算方法,它具有因次和谐及在h_p/b_1=3.0处连续的特点。用既有铁路线的粘性土桥墩局部冲刷深度实测资料验证表明:计算值与实测值基本一致。
Based on the analysis of measured local scour depth data of clay pier and follow the principle of harmony due to subharmonicity, the calculation method of local scour of the clay pier is obtained. It has the characteristics of order harmony and continuity at hp / b_1 = 3.0. The test data of the partial scour depth of the clay pier in the existing railway line show that the calculated value is basically the same as the measured value.
