摘要：
More and more attention has been focused on the study of the construction technology of highway tunnel considering environmental protection with the development of national economy and social progress. Based on the actual conditions of Lao-shan highway tunnel in Nanjing City, A new environment protection structure, called shed-tunnel structure, is developed. Synthesizing numerical analysis of five different structure style is made from three aspects, that is the bending moment, axial and shearing force, by finite element method software ANSYS. Finally we conclude that the shed-tunnel in the entirely arc style is the optimizing one.
