摘要
本文介绍了陡岭子隧道的设计与施工。陡岭子隧道全长690米，连接丹东和本溪。本文会详细讲述隧道的形状、防水措施、在不同地质情况下的施工方法、在施工期及其后期结构及周边的监控措施。
本文重点讨论了浅埋段的支护设计与验算。衬砌内力计算采用的是荷载-结构法并考虑了温克尔假定下的围岩的弹性抗力。由此得出计算结果：衬砌变形图、弯矩图、轴力图、剪力图，各模型单元的内力清单。
关键词：设计与施工；支护设计与验算；荷载-结构法
Abstract
The paper describes the design and construction of the Doulingzi tunnel with an overall length of 690 meters, which connects Dandong and Benxi. The design shape of the tunnel, the prevention of unfavorable conditions caused by underground water, the digging methods vary to different ground conditions, the structure health and surrounding condition monitoring during and after the construction period will be specified.
The main point of the paper is the support design and analysis for the section of the tunnel in the shallow. The load-structure method is being used, with consideration to the resistance by the rock or soil around it with the Winkler assumption. And at last, the final result, including the value of the lining deformation, the moment, the shear, the internal forces will all be listed by numbers and drawn by the chart.
Key words: design and construction; load-structure method; the support design and analysis
