| 1 | 振动条件下EPS缓冲层对挡土墙受力与变形影响的水平条分法模型研究显示文摘基于考虑时间因素的显示有限差分原理,提出水平条分法数值模型,分析铺设在挡土墙背的EPS(Expanded Polystyrene)土工泡沫缓冲层对振动作用下挡土墙的受力与变形的减震作用。模型中EPS缓冲层为线弹性材料,墙背填土滑楔体被划分为若干个水平土层,每一个水平土层的边界受力与变形分别采用与应力相关的线性弹簧模拟。计算得出振动加速过程中挡土墙背不同高程位置各土条随时间而变化的压力和压缩变形值。以加拿大皇家军事学院岩土工程中心完成的3个室内缩小比例的EPS缓冲层挡土墙振动试验为计算实例,对比研究不同弹性模量的EPS缓冲层减震作用的理论计算结果和试验监测结果。研究结果显示,在水平振动加速度达到0.9g的整个加速过程中理论模型分析预测的沿挡土墙背高程分布的压缩变形以及最大压力与试验监测结果相当一致。该模型的提出,为分析和预测采用EPS土工泡沫作为抗震缓冲层的挡土墙受力和变形提供了可行的方法,对挡土墙的抗震设计有较好的应用价值。 | 汪益敏 Bathurst R J | 2008 | 土木工程学报2008，41，10： | 9 |
