In this paper,the constructing、technology and safety measures for class Ⅱ/Ⅲ soft and crushed rockmass are described in Inzuiyan tunnelling,which is valuable referece to the similar excavating works.

Advances in tunnelling and underground engineering in China are briefly described, and the construction methods and auxiliary processes employed in tunnelling and underground engineering are introduced with some key problems to which attention should be paid during construction.

In the wake of incessant reduction of explorable land plot within urban area underground, shield tunnelling is facing more and more challenges that may emerge,one of which could be such,under the condition of hyper shallow oveburden measured less than 2 times of shield diameter,as how can shield tunnelling tackle with.
