| Abstract: | Studying on the central commercial plaza in Zhuzhou,The article adopts the retaining scheme of manual digging bored piles with two prestressed anchors for the deep foundation pit,based on the engineering geological and hydrogeological condition. Meanwhile,the internal force and deformation of retaining structure was carried out calculation based on incremental method. Through the site monitoring and analysis,It show that the retaining scheme is safe and reliable,and the deformation of deep foundation pit is controlled effectively. |
