Silent barrier of high-speed railway is generally how much load
This not only to the country caused by the heart of the loss, but also played a role in the destruction of the city landscape.
2, what kind of surrounding environment to adapt to set the sound barrier Currently, when talking about traffic noise management problems, always think of the first application of sound barrier to solve the problem. Since the nineties of last century, China in Shanghai, the first in the city after the use of sound barriers barrier, the other metropolis in the country to follow suit, the viaduct bridge on the sound barrier like mushrooming. In fact, as in the city center area to build sound barrier its effect is minimal. If the design is not correct, but also increase the noise pollution.
1, Overview With the rapid development of China's road network, sound barrier as a solution to the current traffic noise problem, has been more and more applications. However, from the current domestic built sound barrier effect, some are not very good, to the country and the people caused unnecessary waste. The main reason for this is that most of the sound barrier design is not scientific basis, blindness is relatively large. Where to set the sound barrier, and how to determine the length of the sound barrier (L), sound barrier height (H) and other parameters are determined by the feeling. Based on years of experience in sound barrier research and design practice, the author attempts to give the practical method and empirical formula of the above parameters in the design of sound barrier, which is designed and used by designers in the future sound barrier design.
