  In the context of ultimate bearing capacity of steel lined reinforced concrete penstock (SLRCP) containing flaws, the use of the elastic modulus reduction method (EMRM) in conjunction with curve beam based internal force calculation is presented.The corrosion models for steel bar and lining are introduced from the literature.The SLRCP is considered bearing load together with lining and reinforced concrete, and its internal force is determined based on a simplified curve beam model.T he element bearing ratio of SLRCP is given through the internal force and sectional strength, and is employed by the EMRM The change of ultimate bearing capacity of some typical SLRCP within their operating life is then evaluated.

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.

鹅公带滑坡体位于乐昌峡水库库区上游约1.3km的右岸侧,库区河道狭窄,滑坡涌浪会对库区岸坡和挡水大坝等产生明显的不良影响.根据鹅公带滑坡体分布的特点,对其滑坡涌浪影响进行水力模型试验,模拟了滑坡体的下滑过程和滑坡速度,对滑坡涌浪的浪高、漫坝涌浪水量、挡水大坝的涌浪动水压强等特性进行分析,供工程设计和运行参考.
