摘要:
采用阵列式活动门装置开展了偏压(斜坡)条件下的活动门试验,通过粒子图像测速技术得到了填料断面全场位移与剪应变,并通过载荷计准确测得了活动门与周边固定部分随活动门下沉过程的竖向荷载变化。采用离散元(DEM)数值模拟探讨了活动门距坡脚距离的影响规律,对活动门下沉过程中填料颗粒旋转、主应力偏转与力链分布等细观力学机制进行了分析。结果表明:活动门下沉过程中,荷载更迅速地转移到坡脚侧,随后更多地转移到深埋侧,最终两侧荷载增量基本相等; 填料中坡脚侧滑移面先于深埋侧形成,两侧滑移面张开角度基本恒定,但深埋侧会随活动门下沉量增加形成新的向外侧扩展的滑移面; 偏压条件下的地基反应曲线与传统活动门试验类似,活动门越靠近深埋侧,土拱效应发挥越稳定; 当活动门离坡脚距离达到2倍活动门宽度时,土拱效应发挥基本保持不变; 随着活动门的下沉,填料中形成了以活动门两侧为拱脚的强力链网络结构。
Abstract:
Array-type trapdoor apparatus was used to conduct trapdoor tests under eccentric loading(slope)conditions. The full field displacement and shear strain of the filling section were obtained through particle image velocimetry technology, and the vertical load changes of the trapdoor and surrounding fixed parts during the sinking process of trapdoor were accurately measured through a load gauge. The influence law of the distance between the trapdoor and the foot of slope was explored through discrete element method(DEM)numerical simulation, and the micro mechanical mechanisms such as the rotation of filling particles, the deviation of principal stress, and the distribution of force chain during the sinking process of trapdoor were analyzed. The results show that during the sinking process of trapdoor, the load is transferred more quickly to the foot of slope, and then more to the deeply buried side, ultimately resulting in a similar increase in load on both sides. The sliding surface at the foot of slope in the filling material is formed earlier than the deeply buried side, and the opening angle of the sliding surfaces on both sides is basically constant. However, the deeply buried side will form a new sliding surface that extends outward as the settlement of the trapdoor increases. The response curve of the foundation under eccentric conditions is similar to the traditional trapdoor test, where the closer the trapdoor is to the deeply buried side, the more stable the soil arching effect becomes. When the distance between the trapdoor and the foot of slope reaches twice the width of trapdoor, the soil arching effect remains basically unchanged. As the trapdoor sinks, a strong force chain network structure with arch feet on both sides of the trapdoor is formed in the filling material.
