摘要
国道307、207线阳泉市绕城改线工程中桑掌隧道穿越多个采空区,利用有限开采全盆地残余移动变形数学模型,通过C语言编制计算程序,对矿区长2100 m、宽1500 m范围进行残余沉降计算,进而提取研究区域内隧道轴线所在点的沉降结果,得到隧道轴线的残余变形值。计算得出的地表残余变形值均满足规范容许值,可以推断桑掌隧道采空区场地基本稳定。
The Sangzhang tunnel passes through several mined-out areas in the Yangquan city diversion project of national highway 307 and 207.using the mathematical model of residual movement and deformation in the whole basin of limited mining,the calculation program is compiled by C language.the residual settlement of the mine area is calculated in the range of 2100 m in length and 1500 m in width,and then the settlement result of the point where the tunnel axis is located in the study area is extracted,and the residual deformation value of the tunnel axis is obtained.The calculated surface residual deformation values all meet the allowable values of the specification,so it can be inferred that the goaf site of Sangzhang tunnel is basically stable.
