Its engineering hub building is a double-curvature arch dam, which is 210 meters high.
Many large-scale engineering projects, like dam, use these two prefect tools for efficient management and continuous control [5].
To sum up, depending on character of hydropower dam engineering concrete pouring construction stage, the collision avoidance system bring real time monitoring to fruition by making effective use of GPS.

Study of the cracking resistance assessment of concrete based on the anti-cracking safety coefficient method Xuefeng Song1,a, Chao Li1, Zhihong Fan1 1 CCCC Fourth Harbor Engineering Institute Co.
Introduction Although the concrete cracking resistance assessment method (application of the anti-cracking safety coefficient) is evaluated by Chinese industrial standard "Technical Specification for Thermal Cracking Control of Mass Concrete of Port and Waterway Engineering"(JTS 202-1-2010, Appendix C) scientifically[1], but the application of the anti-cracking safety coefficient is rarely due to the computation is too complicated.
(3) Assessment of the cracking resistance: calculating the anti-crack safety coefficient K according to Chinese industrial standard "Technical Specification for Thermal Cracking Control of Mass Concrete of Port and Waterway Engineering"(JTS 202-1-2010, Appendix C). as shown in Equation 1-1: fsp(t)/σs(t)=K (1-1) In the Equation 1-1, K is the anti-crack safety coefficient, up to the concrete crack resistance, the concrete has good anti-cracking performance when K≥1.4; σs(t) is the concrete tensile stress calculated value for the age t, in this study it is the actual tensile stress when the temperature of the specimen drops to the average ambient temperature 25℃ in the thermal stress test; fsp(t) is the splitting tensile strength of concrete at age t, which is the splitting tensile strength of the specimen curing by the environment simulation test system in this study .
