Abstract

The technologies for shield tunneling in heterogeneous ground are very important. The development of technologies for shield tunneling in heterogeneous ground is introduced. The development of technologies for shield tunneling in heterogeneous ground in China is presented in terms of definition of heterogeneous ground, problems met during shield tunneling and causes for collapse. The secondary damage for shield tunneling induced by deephole blasting is introduced in detail. The reflecting on technologies for shield tunneling in heterogeneous ground is proposed. The author suggests that the development of shielddedicated equipment technology is the key to successful shield tunneling in heterogeneous ground.
