The cut-and-cover method is normally used in the construction of works connecting surface roads and underground tunnels, which causes great environmental impacts to the ground. Ground Penetrating Shield Technology (GPST) is an effective way to solve this problem. Based on an experimental project, this paper demonstrates shield tunnel deformation control techniques, such as segment stabilization, synchronous grout control, and improvement of joint stiffness, by analyzing and calculating the influential factors of tunnel deformation. This extends the application of shield tunnelling and provides new ideas for tunnel planning and designing.
