根据泥沙起动平衡理论，导出了丁坝坝头局部冲刷深度计算公式，并用黄河下游原型观测资料和室内试验资料对公式进行了验证。该公式考虑了河床组成的粘结力和重力两种不同性质的抗冲作用，并采用黄河实测资料对综合系数进行率定。
According to the theory of sediment start-up equilibrium, the formula of local scouring depth of the dam abutment is deduced. The formula is verified by the prototype observation data and laboratory test data in the lower Yellow River. The formula takes into account the impact of two different properties of the cohesion and gravity of the riverbed, and uses the measured data of the Yellow River to determine the comprehensive coefficient.
