Study on the Effect of Resistance Sliding Key Chamber Blasting Construction of a Hydropower Station on Adjacent Buildings Huafeng Deng1, a, Qian Luo2, b, Xianfan Yuan 3, c and Min Zhu 4, d 1College of Civil Engineering & Architecture, China Three Gorges University, Yichang 443002, China adhf8010@ctgu.edu.cn, b735716705@qq.com, c531016073@qq.com, d514385321@qq.com Keywords: chamber blasting; vibration velocity; field monitoring Abstract.
Therefore, at chamber excavation, it's the problem that encountered frequently in hydropower engineering construction to take effective measures to control blasting vibration intensity, such as strengthening monitoring and research on blasting vibration, which is also an important subject [2~5] in disaster prevention project.
Engineering Introduction The dam, built in the 1970s, is a stone masonry arch dam, and after its built for 30 years, there’re various problems in the aspects of dam body, foundation, diaphragm wall, abutment partial drainage and so on, which need for reinforcement.
According to the relative position of resistance sliding key and monitoring points, blasting center distance of monitoring points becomes more and smaller with the blasting excavation of resistance sliding key chamber.
At the last 10m excavation of resistance sliding key chamber, in order to minimize the vibration of the dam and mechanical and electrical equipment, the single dose of blasting was reduced, according to early detection material.

Time, Cost and Quality (TCQ) has become the de facto of managing projects, including engineering projects and it is also used as performance assessment model.
In this response, this study develops a conceptual model ‘4Es’ (Effective, Economic, Efficient, Ethics) for effective managing engineering projects and for performance assessment.
Introduction In this study, a project denotes architecture, engineering and construction (AEC) projects.
Thus achieving VfM in operation management based on spending less (economic), effective and efficient use of material and resource [A-M].

The layout of the viscoelastic materials could be a key point to improve the structure’s performance on vibration reduction.
