摘要
文章以株洲市中央商业广场深基坑为研究对象,根据工程地质及水文地质条件的特点,采用人工挖孔灌注桩加两道预应力锚杆的方案进行基坑支护处理,并利用增量法原理对支护结构内力和变形进行计算。通过现场监测分析,证明该基坑支护方案是安全可靠的,能有效地控制基坑的变形。
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.
