软基水闸下游河道河床的抗冲刷能力较低,且水闸的泄洪水流条件较复杂,其泄洪消能防冲问题是工程设计和运行极为关心的问题。通过对水闸下游河道消能水位选取、消力池尾坎顶高程、池深、池长及下游海漫段布置等分析,得出了水闸下游消能工布置的优化方法。本文成果可供类似工程设计和运行参考。
某高速公路的路基设计标高为2.65~2.95m,该高速公路所经过的某运河河堤标高约为4.8m,由于公路主线的设计标高低于目前河堤标高、受客观因素影响,只能挖开河堤回填河道做公路路基,原有河道将无法满足泄洪及生态用水要求,因此,高速公路所涉的运河段需要改移(新开河).通过水工模型试验研究,优化了设计方案布置形式,节省工程投资.本试验研究成果,可为同类工程设计和建设提供可借鉴的经验.
