| 摘 要： | 采用简易、快速、经济的洞壁应力恢复法对某工程边坡勘探平硐洞壁应力场作了系统测试, 并采用FLAC2D软件对测试成果作了斜坡初始应力的反演分析。结果表明, 斜坡应力场随深度变化具有明显分带性, 应力量值随硐深曲线具有典型的驼峰式特征, 与理论分析结果相符, 表明该方法能较好地应用于斜坡应力场的系统测试和研究。成果对认识斜坡岩体的变形破裂及卸荷特征等具有重要意义。 |
| 关 键 词： | 斜坡应力场 应力恢复法 洞壁应力 反演分析 斜坡应力分带 |

| Abstract: | The exploration adits w all stress f ie ld o f one eng ineer ing slope w as system ically tested, adopting the stress restoringmethod w ith simplicity, exped it iousness and economy. Accord ing to test resu l,t the slope stress fie ld w as back- analyzed by FLAC2D. The resu lt ind icated that the slope stress field had dist inct zonation in depth. The curve of stress magn itude in depth had typical hump character istic, w hich corresponds to the theoretical analysis. The outcome is of sign ificance to exam ine the deformation, crack ing and re lie f o f the slope. |
