Concept of the NATM in China and its influence on the numerical analyses on tunnel design and construction with FEM
2008 (English)Conference paper (Refereed)
The concept of NATM has been widely accepted in the fields of both tunnel and underground structure design and construction in China since 1980s. Similarly in the world wide, there are several definitions and explanations in both academy and construction markets. In practice, there is usually a big gap between involved parties in understanding the meaning of NATM. In this contribution, the concept of NATM in China is first reviewed. The influence of the concept of NATM on the numerical analyses on tunnel design and construction is briefly described in terms of FEM. Based on the practical situation in China, discussion focuses on the disadvantage of NATM application. The main causation is due to the different meaning under same name in practice. Suggestions are proposed to the educators who are disseminating the concept of NATM.
