| 摘 要： | 通过对某高速公路边坡上的一个坡面进行锚杆支护,利用FLAC3D软件对该坡面的安全系数和锚杆抗拔力进行数值模拟分析,并且运用正交法分析了锚杆参数对群锚效应影响程度的大小,研究结果表明:在锚杆长度、锚杆间距、锚杆数量中,影响群锚效应最为明显的是锚杆长度,其次是锚杆间距,最后是锚杆数目。

| Abstract: | The paper undertakes the anchor bolt support at some slope of some expressway,adopts FLAC3D software to undertake the numeric simulation analysis of the safety coefficient and the uplift resistance of the slope,adopts the orthogonal method to analyze the influence of the an-chor parameter on the anchor group effect,and proves by the research result that the anchor length has the largest influence on the anchor group effect followed by anchor distance and anchor number. |
