1模拟库水位变化的抗滑桩加固边坡离心模型试验研究显示文摘抗滑桩是边坡深层抗滑最为有效的措施之一,以三峡库区边坡抗滑桩加固工程为背景,利用离心模型试验手段,模拟库区蓄水和水位循环变化条件下失稳边坡的抗滑桩加固机制。详细介绍相应的离心模型试验方法,通过对一系列自然边坡和不同桩间距条件下的模型试验,获得库水位变化影响下的边坡变形、破坏模式和抗滑桩受力,探讨滑坡推力的分布以及不同桩间距条件下的抗滑桩-边坡相互作用机制。测试结果表明,受抗滑桩加固的边坡在水位升降作用下仍发生一定程度的变形并产生裂缝,随着抗滑桩的直接支挡和桩后土体由于不均匀位移产生土拱效应后,边坡变形逐渐得到较好的控制。在本试验条件下,随着桩间距的增大,边坡变形总体上表现为增大趋势,但抗滑桩的受力呈现出先增大后减小的抛物线型变化形态,在某一最适桩间距情况下抗滑桩的抗滑性能得到了最充分的发挥,而滑坡推力表现出复合三角形分布特征。该研究结果为桩土相互作用和库区边坡抗滑桩加固机制分析提供了直接的试验依据,对丰富抗滑桩设计理论和库区边坡的防灾减灾研究具有较为重要的意义。李邵军 KNAPPETT J A 冯夏庭 陈静 2009岩石力学与工程学报2009,28,5:17
