江阴大桥南塔墩地基基础安全监控模型
摘要:江阴大桥南塔墩座落于缓倾顺向高边坡上,其地基岩体由互层状砂、页岩组成,基桩上部20m采取桩周摩擦失效处理。阐述了地基基础安全监测网的构成及监测目的。分别建立了基桩桩顶轴力、摩擦失效段底部轴力、嵌岩段轴力以及外部变形监控模型,并结合监测成果对地基基础安全性进行评价。
Abstract:The south tower foundation of Jiangyin Bridge is located at gentle high slope.The foundation rock is composed of layered sand stone & shale.It is used ineffective treatment at the top 20 meters of the foundation piles.The composition of safty monitor web and monitor position are described.The axial force respectively at tip of the piles,at bottom of the ineffective frictional area,in the rock and the outside monitor model for deformation are established.Combined with monitor data,safty of the foundation is assessed.
