摘要
在抗滑桩设计中,选择何种作用在桩身的滑坡推力的分布形式,直接影响结构内力的大小和结构尺寸。根据膨胀土边坡抗滑桩中的测斜管观测数据,假定了合力分布的不同形式,基于Winkler弹性地基梁方法开展反演计算并结合现行的支挡结构设计规范,认为抗滑桩所受合力的分布形式采用三角形分布较为合理,为相关涉及膨胀土边坡的支护设计提供参考。
In the design of anti-sliding pile, the selection of slide body thrust distribution directly influences the structural in-ternal force and size. According to observation data by inclinometer in anti-sliding pile in expansive soil slope, different thrust distributions are assumed. Through inversion calculation and analysis by Winkler elastic foundation beam with consideration of the present specifications for supporting and retaining structures, it is concluded that triangular distribution thrust of anti-sliding pile is more reasonable. The analysis result provides reference for related support design of expansive soil slope.
