摘要
以土的塑性上限分析理论为基础，结合墙后土体的两种三维破坏模式，在地震作用下推出了适用于长、短挡土墙上主动土压力上限值的统一表达式，并通过算例计算进行验证．
Based on soil plasticity and limit analysis theorem, togethor with two three-dimensional failure modes of cohesionless backfill, this paper presents a general formula of upper bound values of active soil pressure acted on rough retaining walls during earthquakes. These formula in the paper are verified by some calculation examples.
