| 摘 要： | 现场调查表明,锚杆支护能有效提高边坡在地震作用下的动力稳定性.通过采用拟静力法对汶川震区内锚杆支护边坡的地震稳定性进行验算后得知,边坡的动力安全系数随锚杆长度的增加而增大.利用FLAC3D分析了地震作用下锚杆支护边坡的动力响应规律以及锚固参数对边坡动力特性的影响.结果表明,锚固措施能有效抑制坡表加速度的放大作用,地震后...

| Abstract: | By means of field investigation,it is shown that slope supported with anchor has good effect on resisting earthquake.The pseudo-static method was used to analyze the stability of anchored slopes in Wenchuan earthquake region,the result shows that the dynamic safety factor of slope increases with the increase of anchor length.Based on FLAC3D program,the dynamic response regularity and the influence of anchoring parameters on dynamic characteristics of anchored slope were analyzed.It is shown that(1) anchorin... |
