混合模型方法在超大规模输水隧道中的应用
|
摘要
针对某在建超大规模输水隧道,提出了混合模型方法.该方法将局部仿真直接包含在整体仿真中,避免了局部模型分离带来的误差,并且实现了整体仿真与局部仿真的同步.利用显式算法和相关技术,通过实际计算应用,证明了该仿真方法的可行性.
This paper proposed a hybrid-model method based on an ultra-large water conveyance tunnel under construction,which directly performs global simulation and local simulation together,and can avoid the deviation brought by boundary condition gained from global simulation.Using the explicit algorithm and related technologies,it proves this method is feasible through the actual calculation and application.
