超大直径泥水盾构软弱地层到达掘进变形规律研究——以苏埃通道工程为例

Puntos clave

• This research aims to explore the deformation patterns during tunneling in deep soft soil using a large-diameter slurry shield.
• Conducted field monitoring with surface settlement and pressure sensors.
• Analyzed deformation impacts during different tunneling stages.
• Assessed groundwater pressure changes in response to tunneling activity.
• The tunneling and tailing phases caused the greatest disturbance to the soil.
• Significant peak deformation rates were observed when the cutting head reached the monitoring section.
• The effects of pore water pressure and surface settlement differed over time, with pore pressure initially increasing then decreasing.
