Abstract In light of the inadequate application of digital experimental techniques in China′s shield design and construction management, and in order to develop a digital experimental platform for shield tunnelling, a system analysis was carried out for the five key techniques involved (i.e., geomechanics parametric modeling, parametric modeling and analysis of cutters and the cutterhead, total load analysis for shield tunnelling, analysis of interface support force and rock-soil deformation and physical digital simulation of the cutterhead driving process) based on the key and challenging points as well as the research status regarding digital experimental techniques. This paper also verifies the scientificity and rationality of this model by comparing the calculated and measured results based on one project case and provides a reference for the design, manufacture and construction of shield machines.
