公路隧道围岩压力与中隔墙应力计算研究

Study on Highway Tunnel Surrounding Rock Pressure and Middle Wall Stress Calculation

在城乡经济不断发展的今天,对交通基本措施的建设正在不断的加强,公路的等级也越来越高,对公路隧道的建设也越来越重视。但是,从整体上来说,我们的国家的公路隧道建设起步得比较晚,发展程度还不是很高,很多的技术和研究相比较于西方发达国家来说还有很长的一段路要走。在本篇文章中笔者将理论与实践想结合,运用地球物理学的基本原理,推导出隧道围岩环向地应力的计算表达式。该表达式把比较复杂的隧道模型精简成为一个拱进行计算,与此同时还在隧道工程实例中进行了有效的实践检验。让理论应用于实际。

In urban and rural economic development, the construction of the basic measures of traffic is ever increasing, the level of the highway is increasing, the construction of the highway tunnel is more and more valued. However, from the whole, China＇s highway tunnel construction started quite late, the degree of development is not very high, there is still a long way to go for China＂ lots of technologies and researches compared to the western developed countries. The author combined theory with practice, used the basic principles of geophysics, deduced the calculation expression of the tunnel surrounding rock ring crustal stress. The expression streamline more complex tunnel model to become arch to calculate, at the same time, effective practice inspection was carried out in tunnel engineering example.
