摘要
根据水力学基本原理,建立了分期导流过水围堰水力计算模型,联合求解过水围堰和束窄河床的过流能力及相应的沿程水位、流速和上下游水位落差等水力要素。采用2005年向家坝坝区河段的实测资料对该模型进行了验证,计算结果与实测资料符合良好,可用于工程实际导流决策中。
Based on the hydraulic computation theory, a hydraulic numerical model describing an overflow cofferdam during multi-phase diversion is presented to achieve the discharge capacities, streamwise water levels, velocities of both overflow cofferdam and narrowed river. The validity of the model was checked with the observed data of the Xiangjiaba Project in 2005. The calculated values are in good agreement with the observed data.
