摘要
松雅湖隧道位于高低湖区交界处,受力复杂,景观设计要求高。为使结构设计既能满足交通需求,又能与周边环境有机融合,通过定性类比与定量分析相结合的方法,根据项目的特点对岸上暗埋段横断面形式进行介绍,对水中段采用亚克力顶棚及侧墙镶嵌玻璃2种横断面方案进行比选,并对洞门造型所采用的水波方案及双臂方案进行比选,确定了推荐方案。由于水中段主体结构断面及所受荷载的不对称性,采用有限元方法对其进行数值模拟,得到具体的受力分布情况,同时对结构的抗滑移、抗倾覆、防排水、环境保护等进行介绍。
Songyahu Tunnel is located in the connection section between high water-level zone and low water-level zone with complex stress conditions and high landscape design requirement. In order to meet the traffic requirement and surrounding environment requirement,the cross-section modes of mined tunnel at lake shore are introduced; the crosssection scheme of acrylic roof and that of sidewall glass are compared and the shapes of tunnel entrance / exit are selected by means of qualitative analysis and quantitative analysis. Meanwhile,the stress distribution of lake-crossing tunnel is analyzed by means of finite element method; and the anti-sliding,anti-tilt,waterproof and drainage and environmental protection of the tunnel are described too.
