Abstract

Abstract

Based on the three-bore parallel rectangular pipe jacking project at Mingxiulu Station of the Nanning Metro， the construction control measures for small-spacing three-bore parallel pipe jacking were proposed. The investigation into ground settlement and pipe deformation was conducted using numerical simulation and field monitoring. The numerical analysis showed that the ground settlement curve presented a three-peak "wave" pattern， with the greatest settlement occurring at the axis of the middle pipe. The maximum ground settlements with and without implementing control measures were 16.65 mm and 5.46 mm， respectively， indicating that the measures effectively reduced settlement. The range of ground disturbance caused by construction was approximately three times the pipe width when control measures were implemented. Field monitoring results showed a ground settlement ranging from 1.02 mm to 6.12 mm， with larger settlements observed at the launch and reception ends. Key measures， including construction axis control and deflection correction， synchronous grouting， optimization of the construction sequence， channel steel reinforcement， and soil conditioning， were taken during the construction. These measures successfully controlled ground settlement.
