| 摘 要： | 通过地应力现场测试,研究引汉济渭工程黄三隧洞地应力场特征。首先介绍水压致裂法基本原理,然后分析现场测试结果得到了水平主应力量值和最大水平主应力方向,讨论了地应力场特征及地应力对隧洞轴向选择的影响。测试区域内,地应力属于中低应力水平,σ_Hσ_hσ_Z;地应力方向在浅部符合河谷区应力分布一般规律,深部主要受区域构造应力场影响。从地应力角度分析,隧洞轴线选择方向对围岩稳定较为有利。

| Abstract: | The crustal stress characteristic of Huangsan tunnel of Hanjiang river diversion project is studied by in-situ measurement of the stress.The principle of hydro-fracturing method is described at first,and then the quantitative value of the horizontal principal stresses and the direction of the maximum horizontal stress are obtained through analyzing the measurement results.At last,the characteristics of crustal stress field are evaluated and the influence of the stress on tunnel axis selection is discussed.T... |
