But high energy consumption and high water consumption will increase its production cost and make its manufacturing process too complex to be extended in practical engineering.
Furthermore, this new method has many advantages to be applied in practical engineering and it can promote the level of recycling and utilizing waste concrete as well.
Research work in this paper not only improves the reutilizing level of waste concrete, promote the main technical indices of recycled materials, but also developed recycling equipment of waste concrete has much advantages such as energy conservation, portable movement and low investment et al. all these characteristics make this technique to be easily extended in practical engineering, and it can bring better social effect and economic benefits.

Risk Analysis and Assessment for the Face Stability of Tunnel Wang Haitao1, 2,a, Jia Jinqing 1,b 1 State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology, Dalian, China 2 School of Civil and Safety Engineering, Dalian Jiaotong University, Dalian, China; aemail: wht_dalian@163.com, bemail: keyknown@163.net Key words: Risk analysis, Face stability of tunnel, Numerical method, Analytical method.
Introduction Because of engineering geologic condition, hydro geological condition and artificial factor, it is easy to result in collapse of tunnel, which can result in enormous casualties and huge economic losses in mountainous regions.
Strong and urgent social demand for the release of traffic congestion urged decision makers to hurry, which in turns engineers and construction workers involved in the project urged to hurry.
The over-demand and insufficient time affected normal civil engineering process considerably.
