摘　　要：以上中路越江隧道工程从法国布依格公司引进的原用于荷兰"绿心"工程的超大型泥水平衡盾构为例,分析了盾构在推进过程中引起地面沉降的多重因素,并针对这些影响因素,在施工中主要采取了控制盾构切口水压、泥浆性能、同步注浆量和注浆压力的控制以及地面监护等多种措施控制地面沉降,并反馈到信息化动态施工管理中。使地面沉降均控制在设计允许范围内,保证了工程的顺利实施。Based on the practical use in Shangzhong Road river-crossing project of super large slurry balancing shield imported from BOUYGUES of France and used in ＂Green Core＂ project of Holland, multiple factors that caused the settlement while pushing forward are analyzed, In order to control the settlement, measures are adopted to control the pressure of edge, performance of slurry, synchronous grouting amount and grouting pressure, The result feedbacks to informationized dynamic construction management, keeping the settlement within allowed range, making sure of the success of construction

关 键 词：超大型泥水平衡盾构 地面沉降 沉降控制 泥浆性能
