扶壁式挡土墙在坡地建筑中的应用

Application of Counterfort Retaining Wall in Slope Building

采用PKPM 2010软件对实际在建的坡地建筑进行模型分析.根据挡土墙的类型、建筑的层数分别建立6个不同的坡地建筑模型,并进行整体指标分析.结果表明:带扶壁式挡土墙的模型在周期、位移、抗倾覆和抗滑移上都比带一般挡土墙的模型更能满足规范的要求.因此,建议单层坡地建筑宜优先采用扶壁式挡土墙作为其挡土外墙,同时,在外墙有土一侧做好排水的措施.

PKPM 2010 software is used to analyze the model of actual buildings of the slope.According to the type of retaining wall and the storey number of buildings,six different slope building models are set up respectively and the overall indexes are analyzed.The results show that the model of counterfort retaining wall can better meet the requirements of the standard than common retaining wall in period,displacement,anti-overturning and anti-slip.Therefore,it is suggested that the counterfort retaining wall is preferential forms in singlestorey slope building.Meanwhile,the benign measures for drainage on the side of the wall would be taken.
