基于青藏高原东南地区某特长深埋隧道工程,建立了高精度的山体三维有限元模型。在横洞内钻取了岩芯试样,通过室内试验获得了岩石物理力学参数。采用水压致裂法测得该工程区的现今构造应力,测区现今主应力场以南西‑北东向挤压为主。地应力数据转换角度后,通过多元线性回归的原理,得到构造应力的回归公式,回归公式和回归系数满足显著性检验。计算得到隧道工程区域的构造应力场,反演计算精度良好,计算结果符合实际隧道工程区域的构造特征。隧道轴线上的主应力分布规律表明:该隧道受到强烈的构造挤压作用,岩体内赋存较大的水平应力,最大水平主应力超过62 MPa。为避让大断层而选择的隧道走向与最大水平主应力小角度相交,这将有利于隧道围岩的稳定。隧道埋深较浅的里程地应力特征为

A high-precision three-dimensional finite element model of the mountain terrain was developed for an exceptionally long and deeply buried tunnel project in the southeastern Qinghai-Tibet Plateau. Core samples extracted from lateral tunnels facilitated the acquisition of physical and mechanical parameters of rock through in-lab testing. The current tectonic stress within the project area was assessed using the hydraulic fracturing method, revealing a prevailing compressive stress orientation from southwest to northeast. Tectonic stress data were reoriented and analyzed using multivariate linear regression, yielding a regression formula for tectonic stress that met the criteria of statistical significance. The calculated stress field in the tunnel zone exhibited high accuracy when compared to the actual structural features of the region. The principal stress distribution along the tunnel's axis suggests significant tectonic compression. There are high horizontal stresses within the rock mass, with the maximum value exceeding 62 MPa. This supports the strategy of tunnel crossing a major fault at a small angle, which enhances the stability of the surrounding rock mass. In shallow buried sections, the tectonic stress signature is characterized by
