［摘要］地下空間的開發(fā)是緩解城市用地緊張的有效方法，地下環(huán)廊作為各地塊之間的車庫聯(lián)絡(luò)通道顯得尤為重要。依托武漢王家墩中央商務(wù)區(qū)地下交通環(huán)廊工程，通過有限元模擬以及實測數(shù)據(jù)的分析，研究了基坑與地下環(huán)廊的變形特點，分析了工程樁抵抗變形的能力。結(jié)果表明：本次分析數(shù)據(jù)與監(jiān)測數(shù)據(jù)較為吻合；工程樁作為環(huán)廊的保護措施，效果明顯，在很大程度上約束了環(huán)廊的變形；環(huán)廊不僅發(fā)生位移而且出現(xiàn)了一定程度的軸向扭轉(zhuǎn)。

Abstract: The development of underground space is an effective method to relieve the tension of urban land use. The underground loops as the communication channels between the blocks are very important. The finite element (FEM) analysis was carried out to study the deformation characteristics of foundation pit and underground loop, based on central business district of Wuhan-Wangjiadun. Also, the ability of resisting deformation of piles was studied.The results show that the analysis data is consistent with the measured data. Piles as protection measures, the effect in resisting deformation is obvious. The underground loop occurs axial torsion besides displacement.
