Aimed to solve the problem that the mass concrete structures are apt to crack in underground engineering, this paper makes some research from the view of crack resistance performance of polypropylene fiber concretes. Since polypropylene fiber achieves waterproof through realizing of crack resistant, blending polypropylene fibers into concretes can reduce early contraction deformation of concretes, hinder emergence of plastic shrinkage cracking and improve impermeability of concretes, and its construction technology is simple. In practical application of this in anti-cracking and anti- seepage concrete structures in the International Terminal project of Hangzhou Xiaoshan International Airport, we find that mix of polypropylene fibers with concretes clearly improves anti-cracking and anti-seepage performance of concrete structures and meets design requirements of basements through measuring temperature and observing cracking condition of the mass concrete structures of basements on site. The project can provide experience for reference to similar projects.
