Abstract Research purposes: There are many uncertainties in the construction of shield directly cutting pile，the technology is not mature enough． In this thesis，relying on the actual project，the experience and the technical parameters of the construction aspects of the shield directly over the pile were summed up for further study of the shield directly over the pile technology to make a direct reference for similar projects．

Research conclusions: Through the study of the problem，such conclusions are obtained: ( 1 ) To control the the incisions pressure fluctuations in the value of less than 0． 1 bar; ( 2) Difference of the slurry flow and the promoting speed should be match，at the same time ，to control the amount of overbreak; ( 3) The thrust should be in the range of 9 500 ～ 100 000 kN; Shield driving speed is controlled at 10 ～ 20 mm / min． Cutter speed in control of 1． 0 ～ 1． 2 rpm / min is appropriate，and at the same time to control the cutter torque between the range of 0． 9 ～ 1． 2 MN?m．

Key words： slurry shield pile group technical measures construction parameters
