城市水下隧道最小埋深的设计方法研究

基于城市水下隧道环境条件的特殊性,以长沙市营盘路湘江隧道为依托,提出水下隧道最小埋深的设计标准流程:首先,在对日本经验法、挪威经验法和顶水采煤法等工程经验法分析的基础上,提出隧道最小埋深的初始值;然后,通过线路纵断面的拟定,并结合典型隧道工程类比,不断调整该初始值;最后,结合数值分析法的验算结果,确定隧道最小埋深的合理...

Research on Design Methods for Minimum Burial Depth of Submerged Tunnels in Cities

Based on particularity of environmental conditions of submerged tunnels in cities,this paper proposes a standard design procedure for the minimum burial depth of submerged tunnels on the basis of Xiangjiang Tunnel at Yingpan Road of Changsha: first,propose initial value of the minimum burial depth of tunnels based on analysis of the Japanese empirical approach,Norwegian empirical approach and coal extraction on topside of water,etc.;second,adjust initial value continuously by drawing up longitudinal section...
