Mechanism of Crack Extension in Rock You-Liang Chen 1,a, Jun Sun2,b 1Department of Civil Engineering, Shanghai University, Shanghai 200072, China 2Department of Geotechnical Engineering, Tongji University, Shanghai 200092, China ae-mail:chenyouliang2001@yahoo.com.cn, be-mail:sunjunk@online.sh.cn Keywords: crack, initiation and propagation, sandstone, creep Abstract.
And the creep behaviour of rocks was also theoretically and experimentally studied by some scientists and engineers.
KIC2 should be considered as an important parameter on design and computation of rock engineering. 1 Introduction Rock fracture mechanics can give explanation of rock failure, crack occurrence and propagation for a wide range of geological and engineering situations.
The creep behavior of rock is a very important phenomenon for many engineering geological problems, too.
(i)The parameter KIC2, which is defined as creep fracture toughness of rock materials and smaller than KIC, is a very important parameter for rock engineering.

That is, while the system detection error is considered the reliability index is closer to the actual engineering situation.

With this method, the concession period decision model is established based on traditional NPV and from perspectives of different stakeholders [[] Qiming Li and Liyin Shen: Journal of Industrial Engineering and Engineering Management (In Chinese) Vol. 14 (2000), p. 43-46 ].
Considering the influence of the investor’s equity capital and risk return rate on the discount rate, some scholars have proposed concession period calculation model for BOT project based on the MM theory and CAPM[[] Xuan Qin: Journal of Industrial Engineering and Engineering Management (In Chinese) Vol. 19 (2005), p. 60-63 ].
Further research took social benefits as a decision criterion of the concession period decision model [[] Lili Zhao and Deqing Zhao: Journal of Industrial Engineering and Engineering Management (In Chinese) Vol. 23 (2009), p. 125-130 ]. (2) Related research based on game theory.
Some scholars took the construction cost and the concession period as decision variables to establish a game model and have analyzed the investor and the government's optimal strategy [[] Hongwei Yang, Jing Zhou and Jianmin He: Journal of Industrial Engineering and Engineering Management (In Chinese) Vol. 17 (2003), p. 93-95 ].
Imitating construction period and construction cost, and the concession period in a given return on investment and the level of confidence will be calculated [[] Zhang X Q: Canadian Journal of Civil Engineering Vol. 33 (2006), p. 622-631 ].

Summary of performance and the application of the concrete filled steel tubular structures Jing Gong1, a, Jia Li1,b *, Yue Tang2,c and Yuan miao3,d 1School of Civil Engineering, Northeast Dianli University, Jilin,Jilin,China 132012 2Zhoushan Power Supply Company,China Power Grid,Zhoushan,Zhejiang,China 316000 3Haikou Power Supply Bureau, China Southern Power Grid,Haikou,Hainan,China 570100 aemailgj6625@sina.com, blijialjlijia@126.com, c630301438@qq.com, dmiaoyuan100@126.com Keywords: concrete filled steel tube; ultimate bearing capacity; high-rise buildings; power transmission tower.
In recent years, with the deepening of theoretical research and production of new construction technology, engineering application is increasingly wide[1].
40 years, with the rapid development of national economy, the concrete filled steel tube structure of the high-rise building engineering and large span Bridges in our country has been effectively applied in engineering, and promote the development of construction technology. 4.1 Application in the high-rise building project: Compared with common steel reinforced concrete column and column, concrete filled steel tube composite column is especially lightweight, saving steel, convenient construction, and better rigidity.
Built in 2002 in guizhou BeiPanJiang bridge (figure.2), is China's first railway concrete filled steel tube arch bridge, is also the world's largest single span railway arch bridge, arch foot center span of 236 meters, is the deck basket type concrete-filled steel tube arch. 4.3 Used in transmission line engineering: Transmission lines are important lifeline engineering, when crossing the river, often need to erect up to hundreds of meters of large span transmission tower, the biggest span can amount to thousands of meters.
This kind of composite structure can adapt to modern engineering structure to the needs of the development of large span, tall, overloading, it is based on this advantage, concrete filled steel tube is more and more widely used in various kinds of structural engineering, and has obtained the good economic efficiency and the construction effect.

Traditional applications of PET materials can be found in a wide range from the packaging industry, the apparel industry where polyester fiber is an excellent choice, the mechanical engineering where textiles made of PET fiber are generally adopted in conveyor belts and tire cords to bear the external mechanical loadings, to the civil engineering where the thin films or sheets made from polyester are chosen to utilize their high tensile strength and good chemical stability.
This is also an important factor for the determination of materials selection for today’s material engineers.
Actually for metallic materials necking starts after the maximum engineering loading appears.
Though the concept of the Young’s modulus for crystal materials is well defined, from the engineering point of view, secant Young’s modulus may be introduced and usually defined to be the slope of the solid red line in Fig.4 for most engineering materials.
