Abstract Based on the running tunnel from the Ludan village station to the South People Road Station to the Xiangxi Village Station of Shenzhen Metro Line 9, the construction techniques for a shield cutting through a pile foundation in two different cases are described. The parameters of total thrust, advance rate, cutterhead torque, earth pressure, etc., were controlled during construction, which achieved smooth cutting and the successful passing of the pile foundation, controlled the settlement of the surface and an adjacent building, reduced construction costs and impacts on the surrounding environment and shortened the construction period.
