森公地铁车站基坑内支撑变形规律监测分析

On analysis of survey in support deformation law of foundation pit of forest park subway station

给出了某市森公地铁站深基坑支护方案和内支撑监测方案,对基坑变形规律进行了现场监测研究,重点对钢支撑轴力变化进行了现场监测和规律研究。结果表明,钢支撑轴力随开挖深度增加而增加,其大小变化与工况、开挖方式、开挖速度以及温度等因素有关。

The paper provides the supporting scheme and internal support survey scheme for the deep foundation pit in forest park subway station of some city,researches on the field survey of the deformation law in the foundation pit,indicates the field survey and law research on the steel support axial force changes and it is concluded that the axial force of the steel support increases as the excavation is deepened,and its changes are related to the engineering situation,the excavation approaches,the excavation spee...
