摘要: 为了揭示地面沉降对不同盾构施工参数的敏感性,以成都地铁17号线来凤路站—凤溪站盾构区间隧道为例,采用灰色理论对总推力、刀盘扭矩、同步注浆压力等9项控制参数的实测数据进行分析。研究结果表明:地面沉降对盾构施工参数敏感性最主要的3个因素依次为推进速度、注浆压力(注浆量)和螺旋机转速;在成都地区富水砂卵石地层中进行盾构施工时,盾构总推力控制范围为19 000~41 000 kN,刀盘扭矩控制范围为8 000~23 000 kN·m,同步注浆压力为1~3 bar;灰色理论模型能客观、准确地反映富水砂卵石地层盾构施工参数控制与地面沉降之间的关系。

Abstract: In order to reveal the sensitivity of ground settlement to different shield construction parameters, taking the shield tunnel between Laifeng Road station and Fengxi station of Chengdu metro line 17 as an example, the measured data of 9 control parameters, such as total thrust, cutter head torque and synchronous grouting pressure were analyzed by using grey theory. The research results show that the three most important factors affecting the sensitivity of ground settlement to shield construction parameters are propulsion speed, grouting pressure or grouting amount and screw machine speed in order. When shield construction is carried out in the water rich sandy pebble stratum in Chengdu area, the control range of total thrust of shield is between 19000~41000 kN, the control range of cutter head torque is between 2 000~23 000 kN·m, and the synchronous grouting pressure is between 1~3 bar. The proposed grey correlation analysis model objectively and accurately reflects the relationship between the control of shield construction parameters in water rich sandy pebble stratum and the ground settlement.
