Abstract：The creation of ground pass shield tunnelling(GPST) method has conquered the disadvantage of constructing working shaft for shield launching and arrival which is a typical of traditional tunnelling method，and making an innovative turning point on shield tunnelling history. This paper first presents a detail investigation on the key problems of GPST method by adopting large-scale model test，numerical simulation and in-situ monitoring. The surface settlement characteristics of different crossing stages of GPST method have been revealed. In addition，an engineering application of this new method was carried out in Moling-Jiangjun interval of Nanjing intercity fast track；some key tunnelling parameters and effective measures were explored. Comparison was also done between the monitoring data，model test results and numerical results；it is shown a good agreement with each other；and a sound basis is established for the broad application of GPST method.
