秦岭终南山特长公路隧道围岩变形规律的研究

Researches on deformation regularity of surrounding rock in Zhongnanshan super-long highway tunnel in Qinling

为掌握秦岭终南山特长公路隧道的围岩变形规律,采用SJW-Ⅳ收敛计对秦岭终南山公路隧道进行围岩变形量测,并对所采集的数据应用对数函数和指数函数进行了回归分析,分析结果表明,围岩的变形符合对数函数规律,且实测值和计算值都很小,可保证隧道的施工安全和质量,从而为类似工程提供了参考。

This paper carries out deformation measurement on surrounding rock in Zhongnanshan super-long highway tunnel in Qinling by SJW-IV convergence indicator to grasp the deformation regularity of the surrounding rock,carries out regression analysis on the collected datum by logarithmic function and exponential function,and shows by the analysis results that the deformation of surrounding rock accords with the rule of logarithmic function and has small measured value and calculated value,which can ensure construc...
