摘　　要：以实际工程项目为例,在掌握桥梁设计在高陡边坡隧道斜交进洞工程中的作用的基础上,分析了桥梁桩基础设计及优化、洞口边仰坡防护、隧底挡墙支撑斜交进洞、洞口桥梁与隧道相接、施工平台及道路保通等的工程设计与施工措施,有助于推动隧道斜交进洞施工工作顺利进行,充分发挥工程设计方案实践性,有效提升高陡边坡隧道斜交进洞工程的施工质量。Taking the actual project as an example,on the basis of understanding the role of bridge design in the oblique access of high and steep slope tunnel engineering,the engineering design and construction measures of bridge pile foundation design and optimization,slope protection at the edge of the entrance,retaining wall support for oblique access of the tunnel bottom,bridge and tunnel connection at the entrance,construction platform and road protection are analyzed.It is helpful to promote the smooth construction of tunnel oblique tunnel,give full play to the practicality of engineering design scheme,and effectively improve the construction quality of tunnel oblique tunnel with high and steep slope.
