Dynamic response of debris flows impacting curved joint check dams
文献摘要：
The dynamic impact force of debris flow on dams with a curved upstream face curved was inves-tigated using laboratory experiments and a theoretical approach.Equations describing the impact force and maximum run-up height were derived.The experiments and theoretical considerations reveal that the impact force and maximum run-up height are mainly controlled by the Froude number(Fr)reduced by the cosine of the channel slope angle(cosα).Both the impact force and the maximum run-up height have a quadratic relation with the modified Froude number(Fr/(cosα)0.5).The experimental data and the results of the theoretical approach are in good agreement,indicating that the theoretical approach can be used in practical applications.It is concluded that the com-parison between the curved-joint dam and the more conventional sharp-joint dam shows no dif-ferences in the maximum impact force and run-up height for the same modified Froude number.With the sharp-joint dam,the peak values of the impact force are reached more quickly than with the curved-joint dam.
