梧桐山上、下行隧道间距的确定

Interval between Two Tubes in Wutongshan Tunnel

梧桐山隧道上、下行线间距的确定突破了设计规范关于两座平行隧道及小线间距的规定。文中概述了本隧道线间距的设计依据和理论论证,并对设计计算方法和现场试验结果进行了分析。

The interval between the upgoing tube and downgoing tube in Wutongshan tunnel is less than the limitation between two tubes given in design specification . This paper describes the design basis , theory and the design calculation method, moreover , analyzes field test results .
