| 摘 要： | 对于高速铁路大断面黄土隧道严格的设计计算而言，黄土隧道围岩的弹性抗力系数、变形模量和压缩模量十分重要。以郑西客运专线大断面黄土隧道工程为依托，利用现场平板载荷试验研究大断面黄土隧道围岩水平方向和拱底竖直方向的弹性抗力系数、变形和压缩模量，并提出与隧道埋深有关的弹性抗力系数、变形和压缩模量的参考计算公式。

| Abstract: | Elastic resistant coefficient,deformation and compressive moduli of surrounding rock in large-section loess tunnel are very important for design of tunnel. Based on the project of large-section loess tunnels along the new passenger dedicated line(PDL) from Zhengzhou to Xi'an,the elastic resistant coefficients,deformation and compressive moduli of surrounding rock in loess tunnels have been studied horizontally and vertically by plate loading tests. The formulas for these parameters mentioned above which are related to buried depth of tunnel are also provided. |
