Abstract: A rectangular pipe jacking machine is adopted in construction of the underground passages between North Huaqiang Station and Huaxin Station in Shenzhen, which are characterized by a large section, small spacing,a shallow overburden, parallel construction of several jacking pipes, and passage over a metro tunnel and under underground pipelines. A numerical model is established and the simulation method for the grouting pressure and the function of the pipe jacking machine head is discussed and improved, and the effect of pipe jacking construction on the surrounding environment is analyzed. The results show that: the surface settlement trough caused by rectangular pipe jacking construction complies with the Peck Formula, and ground loss plays a leading role in the formation of stratum displacement; with serial construction of several jacking pipes, the shape of the surface settlement trough changes from a "V" to a "W" and the vertical displacement of the shield tunnel superimposes continuously; and pipe roof support effectively decreases the deformation of ground surface and underground pipelines.
