摘　　要：介绍了低桩承台挡土墙基础结构采用竖向弹性地基梁法计算的两种模型:一种是由桩基础承担承台底面以上全部荷载作用,另一种是由地基土与桩基共同承担承台底面以上全部荷载作用。提出两种计算模型的判别条件以及设计时必须遵循的要求,为低桩承台挡土墙结构的设计和计算提供了依据。This paper describes the two models by using vertical elastic foundation beam method to calculate the low pile cap retaining wall base. In one model, piles undertake all load above underside of the cap; in the other model, subsoil and piles work together to undertake all load above underside of the cap. Meanwhile, this paper describes design requirements and discriminant conditions of the two computational models. This paper provides reference to design and calculation of low pile cap retaining wall structure.
