摘要
为有效提高常规悬臂式结构支撑高度,提出二级垛式新型悬壁式挡墙结构,该结构采用类似减压平台挡土墙整体土压平衡计算模式,综合考虑整体平衡及第二破裂面影响,合理选择各级挡墙滑动面及整体滑动面,探讨了二级垛式新型悬臂式挡墙的土压力计算方法,通过工程实例对比研究显示,二级新型悬臂式挡墙墙背受力更合理,稳定性也优于单级挡土墙,该方法为今后类似工程的修建提出了一些设计建议.
Along with the development of the economy, the requirement for the retaining structure is higher. In the framework of the reliving platform retaining wall, the counterfort retaining wall is proposed. Based on the limit equilibrium theory and considering the effect of the second failure surface, the varuous sliding surfacees of counterfort retaining wall is reasonalbe selected. Then the computing method of earth pressure is obtained in the counterfort retaining wall. Subsequently, the earth pressure is demonstrated by comparing with the project case. The comparison results show that the earth pressure and the stablility of the counterfort retaining wall are more reasonable than the common retaining wall. Thus the method has a good applicability for the similar engineering design and construction.
