Introduction In civil, geotechnical and structural engineering researches, the engineering prototype was often reduced the size in accordance with certain proportion to make the similar material simulation test according to the similarity theories.
The real situation in engineering was generally studied by physical model simulation method.
The test data of model could be converted the data of prototype by the similarity relation so as to solve many complex engineering subjects [1-2].
With the development of measurement technology and the application of all kinds of high-quality innovative model materials, the simulation test was widely used in many cases and it would become a modern experimental research method in the engineering research.

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.
