摘要
基于拱梁法 ,通过把围护结构分析中常用的弹性抗力法与拱梁法有机地结合在一起 ,将拱梁法改造成为计算拱形围护结构的一种方法。这种计算方法能考虑拱脚桩变形的影响 ,能考虑有支撑的情况 ,在开挖线以下拱脚桩和拱壁假定由土弹簧约束 ,因此更合理地反映了拱形围护结构的实际情况。该方法计算所需准备的数据与弹性抗力法类似 ,所需输入数据少 ,计算速度快。通过工程实例计算表明 ,该方法的计算结果与实测结果吻合较好 。
In this paper,the arch?beam method is rebuilt to analyze the arched retaining structures in deep foundation pits It happened that the subgrade elastic?reaction method is involved,which is a common method for the retaining structures The influences of both deformations on springing pile and strut are considered Both the springing pile and the buttress are assumed to be restricted by soil springs under the bottom of excavation It needs few input data and shorter running time to use the proposed method A practical example shows that the result of the proposed method is reliable
