摘要
山地公路隧道中,出于通风等需要,往往需要设置风机洞室群。风机洞室群结构复杂,多与行车主洞相贯通,且断面跨度较大,洞室间距较小。因此,保证其安全与稳定是工程的难点。采用三维快速拉格朗日分析方法(FLAC-3D),结合某公路隧道实际,给出了公路隧道风机洞室群的数值模拟分析方法,为今后此类工程提供了经验。
In mountainous highway tunnel,ventilator chambers are usually needed.The structure of ventilator chamber is complex and always connected with vehicle tunnels.The span of ventilator chamber is large,but interval between chambers is little.So the safety and stability of ventilator chambers are very important.The three dimensional fast Lagrange analysis method is adopted to make 3D stability analysis of ventilator chamber of highway tunnel and valuable results are obtained for given practical cases.
