摘要
结合西霞院水库(黄河小浪底水利枢纽的配套工程)的水下修复工程,针对水下不分散混凝土的材料及抗冲性能展开研究。为使水下不分散混凝土的性能达到最优,对其各个材料组分开展原材料试验,进而进行材料优选。同时,利用离散元和计算流体动力学耦合的模拟方法(DEM-CFD耦合方法)对水下不分散混凝土进行建模,在不同水流速度下对其抗冲性能进行了评估。
In combination with the underwater repair project of Xixiayuan Reservoir,this paper focuses on the material and impact resistance of underwater non-disperse concrete.In order to optimize the performance of underwater non-dispersive concrete,raw material tests are carried out on its various material components,and then material selection is carried out.At the same time,the underwater non-disperse concrete is modeled by discrete element method and computational fluid dynamics coupling simulation method(DEM-CFD coupling method),and its scour resistance is evaluated under different water flow velocities.
