| 摘 要： | 随着西部地区建设的投资力度逐年加大，地应力测量与研究工作越来越显得重要。通过在新疆西部拟建精伊霍铁路北天山越岭隧道（最大埋深约1100m）工程区进行的水压致裂地应力测量，获得了北天山地区应力场的主应力值及其方向。本文根据地应力测量结果，对工程区应力场的应力状态进行了研究，分析了隧道围岩的稳定性和地质灾害发生的可能性。

| Abstract: | Ground stress measurements and study in western China become more and more important with increasing construction investment in recent years.Hydraulic fracturing in-situ stress measurements were carried out in a working area of a mountain tunnel(with a maximum burial depth of 1100 m) in the North Tianshan Mountains along the proposed Jing-Yi-Huo Railway in western Xinjiang,and the values and directions of the principal stresses in the stress field in the North Tianshan region were obtained.According to the results of the stress measurements,the authors have studied the stress state in the stress field of the working area and analyzed the stability of the surrounding rocks of the tunnel and the possibility of the occurrence of geological hazards. |
