南昌市轨道交通盾构过砂层掘进参数控制

Control of Nanchang City Rail Traffic Shield Tunneling Parameters Passes through Sandy Layer

采用盾构机进行隧道掘进是近年来国内城市地下交通建设中常用的施工方法，掘进参数的设定对掘进施工尤为重要。本案以南昌轨道交通地铁为例，通过对之前砂层地段的研究，对“地面沉降控制”和“盾构姿态控制”进行了分析，确定了掘进参数。

Using shield machine tunneling is commonly used construction method in recent years in the domestic city und-erground traffic construction, driving parameter set ing is parti-cularly important for the tunneling construction. Taking the case of Nanchang rail transit subway as an example, based on the study of the sand area before,“control of ground set leme-nt”and“shield attitude control”is analyzed, and the tunneling parameters were determined.
