摘要

随着国民经济的发展和社会的进步，公路隧道环保型建设技术日益受到重视。以南京—淮安高速公路南京江北段老山公路隧道为依托，提出了一种环保型结构——新型棚洞。采用大型通用有限元软件ANSYS对5种不同棚洞结构型式进行了优化。从弯矩、轴力、剪力3个方面综合计算分析表明，全拱式棚洞是最优方案。

Abstract

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.
