摘要
横向稳定性与抗变形能力是曲线段非埋式桩板路基的重要计算指标,深入分析这种结构的设计与计算方法十分必要。基于现有的简化计算方法,建立非埋式桩板结构的整体式平面计算模型,探讨了曲线段桩板结构的荷载力系,提出了其设计流程与计算方法。实践证明利用该设计计算方法可有效地获得满足工程精度要求的计算结果。
Non-embedded pile-plank subgrade in curve section has two important parameters,i. e. lateral stability and deformation resistance,and it is necessary to study this structure＇s design and calculation method.This paper,depending on current simplified calculation method,established an integral plane model for this structure so as to discuss its loading force system,as a result,proposed the related design process and calculation method,whose results have been proven to meet the requirement of engineering accuracy by practice.
