摘要
以宝中线老头沟隧道为原型，通过对偏压条件下不同开挖方法的对比试验、了解了地表、地中的应力－应变变化规律．试验结果对土质偏压隧道的施工。
Taking the Laotougou Tunnel,an earth tunnel under unsymmetrical loading,as prototype,the author conducted contrast tests of models excavated with different methods.By these tests the variating patterns of stress strain relation on/under earth surface were found out.The results are helpful to the construction of such tunnels,and also to the determination of the regulated “t value” of double track railway tunnel under unsymmetrical loading in “The Tunnel Specification”.
