摘要: 北京地铁六号线朝阳门站1号换乘厅为异型深基坑,且基坑紧邻大型建筑物,确保结构自身及周边环境安全是本工程的重中之重,在控制结构自身变形的方面采取了加强内支撑及增加深浅基坑连接板等方式进行控制,为降低建筑物沉降,主要采取了旋喷桩土体加固的方式进行地层处理。根据监测数据显示:采取以上方法进行加强处理可有效的控制结构自身变形及周边建筑物沉降,可为类似工程提供借鉴作用。

Abstract: The No. 1 exchanging hall at Chaoyang station on line 6 of Beijing Metro, closes to the large buildings, is found to be a unique foundation pit structure. The inner support strengthening technology and shallow and deep foundation pit connecting board adding method is adopted to control the deformation of the structure. Ground reinforcing by means of jet grouting pile is used to control the settlement of the buildings. According to the monitoring data, the adopted technologies can effectively control the deformation of the structure and the settlement of the buildings. The paper can provide reference for similar projects in the future.

Key words: unique deep foundation pit, building, settlement, soil reinforcing
