公路工程路堑与隧道可替代方案的经济分析

Economic analysis of alternative schemes for cutting and tunnel of highway engineering

从工程经济的角度对路堑与隧道工程可替代方案的费用进行分析,寻找可替代方案费用相同时的临界填挖高度值,并尝试给出方案选择开挖的高度判断值。

This article performs, from the view of economic engineering, an analysis of the alternative schemes of cutting and tunnel works, looking for the critical height value of cut and fill when the alternative schemes are of the same cost, tries to give a judgment value of excavation depth the schemes select.
