Outdoor model experiment concerning effective up-to-date improvement type interception wall shape
Ysuyuki Miyaki
Recently, a car traffic noise is one of the big environmental problems. The problem of the sunshiny obstruction etc. has occurred in the interception wall though the installation of the interception wall and the construction of the low noise pavement, etc. are executed as measures of a car traffic noise. Then, the development of the up-to-date improvement type interception wall that can improve the effect of the interception with the height of the wall kept is advanced. However, a current up-to-date improvement type interception wall has a lot of problems such as piling up and making of garbage and the snow a high cost.
An excellent up-to-date improvement device on construction and the maintenance side from a current up-to-date improvement type interception wall was designed, designed, and it aimed at the outdoor model experiment, and then, it aimed at the CA method and it aimed to propose one shape of a new up-to-date improvement device by doing the noise propagation analysis used in research. First of all, the up-to-date improvement device of new shape was designed, designed, and made from the viewpoint of measures against a current problem etc.Next, the effect of the noise decrease that the up-to-date improvement device possessed in conducting the outdoor model experiment concerning a simple wall and a new up-to-date improvement type interception wall, and comparing the measurement values and examining it was confirmed. Finally, whether it put it to practical use by modeling the outdoor model experiment by the cellular automata method, and confirming the effect of the noise decrease of the up-to-date improvement type interception wall from the comparison and the examination of the calculation value was examined.
As a result, it has been understood that the designed up-to-date improvement device obtains a big amount of attenuation in the high frequency region, and has an effect of the noise decrease that is bigger than that of a simple wall.
