摘要
在城市振动功能区划中,居民文教区和混合区往往难以界定,其原因是两者之间存在着模糊区间。如何解决此类问题是振动区划工作的一个难点。采用二级模糊综合评判方法,将诸多的因素全部参加计算,科学地越过模糊区间,避免靠主观判断带来的偏差,使区划的结果更科学,更合理。
It is difficult to divide the residential and educational functional zone from comprehensive functional zone due to the presence of fuzzy area between them in the the urban vibration functional zoning. How to deal with the problem reasonably is the key steps in this kind of work usually. In this paper, we adopt the secondary fuzzy comprehensive evaluation method and compute all the factors to successfully avoid deviation derived from subjective judgment and make the vibration functional zoning more scientific and reasonable.
