In this article, the construction program of “oppositedirection boring, docking in ground, and dismantling in tunnel” used in Shiziyang shieldbored tunnel on GuangzhouShenzhenHong Kong passengerdedicated railway is presented, with special attention paid to “docking in ground”. Difficulties, such as high docking precision, large water inflow at docking face, and small space for shield dismantling, have been conquered by strengthening the process control of “docking in ground” and by taking assistant countermeasures. In the end, the shield docking has been successfully completed, and good effect has been achieved.
