摘要:
以虹源盛世国际文化城工程（基坑面积93 383 m2，深度15.3 m）为背景，研究临近供能管沟的超大深基坑支护设计及施工的关键技术.结果表明，所设计的基坑支护结构及采用的施工方法可以有效地控制基坑的变形和保护周围环境，围护结构侧向位移最大值为开挖深度的0.23%~0.72%，管沟相邻测点相对位移均小于20 mm.
Abstract:
Based on the background of the foundation pit engineering of Shanghai Hongyuan Prime International Cultural City, the key techniques of the design and construction practice of the super-large deep foundation pit adjacent to the energy supply pipeline are investigated, whose foundation pit area is 93383 square meters and foundation pit depth is 15.3 meters. The results show that the deformation of foundation can be controlled and the surronding environment can be protected effectively by using those techniques. The maximum lateral displacement of retaining structures is from 0.23% to 0.72% of the foundation pit depth. Relative displacement of adjacent measurement points of the energy supply pipeline are less than 20 mm.
