针对重庆骑龙经典工程下卧重庆菜园坝长江大桥南城隧道洞室地基进行定性分析以及二维、三维数值模拟分析。在进行数值分析时采用加载系数法分别对隧道毛洞、隧道衬砌施加岩石自重和各倍数建筑荷载标准值,并对分析结果进行比较。经综合分析表明,高层建筑的施工不会影响隧道洞室的稳定性,高层建筑可以按照常规方法进行设计。并对建筑施工和监测提出限定条件和建议。 Aimed at the foundation of the Chongqing Jilong Long Classic Project, the foundation of the cavern of Nancheng Tunnel in Chongqing Caiyuanba Changjiang River Bridge was qualitatively analyzed and analyzed by two-dimensional and three-dimensional numerical simulation. In the numerical analysis, the loading coefficient method was applied to calculate the rock weight and the multiple standard construction load respectively for the tunnel furrows and tunnel linings, and the analysis results were compared. After a comprehensive analysis shows that the construction of high-rise buildings will not affect the stability of tunnel caverns, high-rise buildings can be designed according to conventional methods. And the construction and monitoring of the proposed qualifications and recommendations.
