Application Study on the Steel Fiber Reinforced Concrete Wen Cui1, a, Qin Luo 2, b 1 Department of Civil Engineering Luoyang Institute of Science and Technology，Luoyang Henan China, 471023 ajanecui9@163.com, bluoqin91@163.com Keywords: Steel fiber reinforced concrete; mix design; tensile strength ; compressive strength; construction technology; mix; pour; vibrate; cure Abstract.
Mix design of the steel fiber reinforced concrete was analyzed based on the engineering conditions.
Under the effect of factors such as load and freeze-thaw, the life of the concrete can be significantly extend because of its crack resistance capacity increase, so the steel fiber reinforced concrete was widely used in road pavements, bridges, building structure, nodes and seismic engineering, waterproof, water, ports, marine engineering works, tunnels, culverts, etc.

Abstract: The box structure is a typical underground protective structure, whose mechanical response to explosion seismic is of great interest in protection engineering.
Introduction Along with the rapid social and economic development and urbanization, considering the need for strategic protection engineering, development and utilization of underground space have become more widely, and tend to be deeper[1,2].
Currently, continuum mechanics is used to analyze the mechanical behavior of underground engineering, but as for deep underground engineering, this method can not explan some phenomena well, the calculation method for a deep underground under blast load should be studied as early as possible.

One is suitable for the scientific research concerning the length of the DCS, and the other is appropriate for the design in engineering application.
Moreover, they concluded that the maximum cooling radius of the DCS in engineering applications should not exceed 960m.
In terms of the requirements presented by reference 2, Eq.15 is more suitable for the engineering applications.
