摘要

摘要: 针对大型输水隧道水锤分析响应分析中由于超大计算规模和非线性强流-固耦合计算造成的数值计算困难,该文提出将混合模型方法应用到大型衬砌输水隧道水锤冲击响应的数值模拟中,通过该方法不仅可以得到输水隧道全程水锤压力,也可以得到关键区域衬砌环管片结构响应。模型中流场部分通过FLUENT计算得到流场节点压力和速度,然后通过初始条件或边界信息施加到结构部分进行LS-DYNA计算,水锤计算时流-固耦合通过基于ALE(Arbitrary Lagrangian-Eulerian)描述的罚函数实现。该文对上海某大直径双线输水隧道在水锤作用下的结构响应进行了分析,结果呈现了水锤压力在长距离输水隧道内的传播以及对衬砌结构的影响。

Abstract: Because of the ultra-large scale calculation and strong nonlinear calculation of fluid structure interactions (FSIs), the numerical simulation and analysis of water hammer impacts in an ultra-large water conveyance tunnel are difficult. The hybrid modeling method is used to simulate water hammer impacts in an ultra-large water conveyance tunnel. The method can not only yield water hammer simulations along the full tunnel length, but also the detailed structural responses of the segment linings. In the finite element model, the pressure and velocity of fluid field is solved with FLUENT and then applied to the structure as the initial conditions or boundary information. The structural field is solved with the finite-element program LS-DYNA. The interaction between two physical fields is realized using ALE (Arbitrary Lagrangian-Eulerian) description. The structural response of a large-diameter double-line water conveyance tunnel in Shanghai under the impact of water hammer is analyzed. The results presented the propagation of water hammer pressure in the long-distance water conveyance tunnel and the effects on tunnel linings.
