| 摘 要： | 针对水利水电洞挖工程瓦斯爆炸后灾害气体扩散危险区域的确定问题,采用基于计算流体动力学理论的CFX模拟软件,结合向家坝水利水电站隧洞施工条件,假定第四层排水廊道内两个有代表性的地点作为瓦斯爆炸发生地点,对洞挖工程瓦斯爆炸后气体扩散进行模拟,分析隧洞各时间下不同区域的动态危险性。结果表明,竖井前瓦斯爆炸主要危险区域为第三层排水廊道及第四层排水廊道端头处,而竖井后为三层灌浆廊道及第四层排水廊道端头处,但对作业人员较多的主厂房和四号施工支洞影响均较小。数值模拟结果和理论分析吻合较好,证明所采用的数值模拟方法是有效和可行的。

| Abstract: | To identify the hazardous areas after gas explosion in excavated tunnel of hydroelectric power station project,CFX simulation software,which is based on computational fluid dynamics,is used to simulate gas diffusion after gas explosion.The simulation uses the tunnel construction conditions in Xiangjiaba hydroelectric power station as an example,selects two representative locations in the fourth drainage tunnel as gas explosion locations to simulate the gas diffusion after gas explosion,and analyses its dyna... |
