摘　　要：结合深圳某过街通道,对CD法施工所引起的地表沉降的主要因素进行了分析,指出CD法施工中浅埋地下通道地表沉降主要是由开挖阶段的初期支护整体下沉和中隔墙拆除阶段的结构变形所组成,并探讨和分析了地层变位的控制措施。Based on the measured data of an underground passage in ShenZhen city, the causes of ground surface settlements induced by the construction of the passage in which the CD construction method was adopted are analyzed. In the construction process by using CD method, the ground surface settlements are caused by the support subsidence in the process of excavation and support deformation in the process of removing the central diaphragm. The measures to control the ground surface settlements are also analyzed.
