I have been an engineer in underground engineering for about 30 years. I have designed or consulted more than 150 tunnel projects from 2000 till present in China. I designed and consulted 6 of the top10 longest tunnels. Their length is between 32km to 12km according to 2015 statistics. These include railway tunnels, highway tunnels, subways, hydraulic tunnels, TBM, etc. The total length of these tunnels is more than 200km. Manage all phases of major complex underground and tunneling projects, from feasibility to conceptual engineering and preliminary engineering through final design and construction. Provide technical expertise and advice to project leadership. Provide direction and guidance to resolve technical issues. I am good at solving geological rock engineering difficulties in tunnels. And those geological rocks are special—soft, high pressure, deformation, etc. I have rich experience in understanding of surrounding rock and engineering treatment. I published 15 papers from 2000 till present, including a book about fault geological activities on engineering (2017). I am a top engineer in this region in China, which includes both theory and experience. I can design tunnel ventilation during operation and construction time.
