Abstract:
Based on a pipe gallery project that passed through a box culvert in Xi'an city, a finite element model of pipe gallery-soil-box culvert was established to explore the effect of the horizontal and vertical combination reinforcement method of horizontal rotary jet grouting pile(MJS)used in the project on reducing the impact of pipe jacking construction process. Two horizontal pile conditions with different pile spacing were established, and the different changes in the force, deformation, and corresponding surface subsidence of the existing box culvert during the jacking process of the pipe under different conditions were analyzed to study the impact of increasing pile density on the reinforcement effect. A comparison was made between the surface subsidence patterns of four sections after combined reinforcement in numerical simulation and the actual monitoring of the surface during construction. The results show that the scheme of using MJS horizontal and vertical pile combination reinforcement can effectively reduce the deformation, internal force, and corresponding surface subsidence of existing box culverts caused by pipe jacking construction during the pipe jacking construction process. Increasing the number of horizontal piles and reducing the pile spacing by 50% does not significantly improve the reinforcement effect. Therefore, in practical engineering, it is necessary to design the number and spacing of piles reasonably and match their positions reasonably. The numerical simulation results of surface subsidence and the actual monitoring results are very similar in value and trend, verifying the accuracy of the numerical simulation.
