摘要
探讨岩体内圆形洞室锚杆支护前后的应力、位移解析解的变化，即围岩特征曲线．结合 Ｌａｂｉｏｕｓｅ 等的系列文章及其他有关资料，应用位移边界理论、 Ｌａｍé公式及弹塑性理论，编制了 Ｔ Ｕ Ｒ Ｂ Ｏ Ｐａｓｃａｌ 及 Ｅｘｃｅｌ 计算程序，评价洞室围岩的应力位移特征．与 Ｌａｂｉｏｕｓｅ 的结果比较，应用本文的计算过程得到的结果极为理想．
Analysis of ground response curves for circular rock openings supported by rockbolts is proposed.By means of Lamé's formula and the elastic plastic theory,and with reference to a series of Labiouse's articles and other ducuments the calculating programs on TURBO Pascal and Excel are developed,and the characteristics of stress and displacement of circular rock openings are analysed.The results obtained in this paper are more satisfactory than Labiouse's.
