摘要
结合某河道整治工程的实施,通过比尺模型试验,对丁坝群设计参数变化时局部冲刷规律进行了分析研究。总结了不同丁坝间距、长度和坝轴线方位角对冲刷坑深度及冲淤位置的影响,并根据试验观测资料提出了丁坝群各坝头局部冲刷深度的分析计算方法,所得结果可供河道整治工程规划设计参考。
Combined with a river channel improvement project, the law of the local scour when the design parameters of the spur- dike group are changed is analyzed and studied herein; in which the impacts from the various spaces, lengths and azimuthal an- gles of axes of the spur-dikes as well as their desilting locations are summarized, and then the method for analysis and calculation of the local scouting depths at the heads of all the spur-dikes are put forward in accordance with the experimental and measured data concerned. The results from all of these can provide references for the planning and design of the relevant river channel im- provement project.
