特殊场地条件下建筑场地类别划分的若干问题
|
摘要
建筑场地类别是根据覆盖层厚度和土层等效剪切波速双参数进行划分的。在工程建设过程中,经常因人为因素导致上述场地条件的改变,这种改变是否可以作为场地类别划分的依据,存在争议;而复杂岩土场地的参数取值也存在差异。对于影响场地类别划分的特殊因素,结合工程实例进行探讨,提出了具体建议,为建筑场地类别的合理划分提供借鉴。
Abstrac: The site classification for construction is divided according to overburden thickness and equivalent shear wave velocity. During the process of construction,it is always changed by this kind of factitious factors. It is controversial that if we can regard this kind of change as an evidence of dividing site classification. And there is also difference in the parameter value of the complicated rock-soil site. To the special factors of the dividing of site classification for construction,specific advice was proposed to provide reference with engineering example to dividing site classification for construction rationally.
