基于已知钻孔的场地类别模糊等值线的建立
摘要:对照现行《建筑抗震设计规范》(GB 50011—2001)场地类别划分方法,应用模糊数学原理,推导了场地类别的模糊二次评价方法,得出了场地类别的模糊向量和模糊特征周期,实现了场地类别划分的连续化;在此基础上,基于收集到的杭州市254个建筑场地波速钻孔实测资料,通过建立场地类别地质模型,实现了场地类别、特征周期的模糊等值线,与实测资料对比,结果表明:由该模糊等值线得出的建筑场地抗震类别与现行《建筑抗震设计规范》给出的场地类别是统一的,模糊特征周期与规范给出的特征周期基本上是吻合的,该模糊等值线对建筑抗震设计具有指导意义。
Abstract:The fuzzy mathematics theory with accordance to the method of site types partition of "Code for seismic design of buildings" (GB 50011-2001)is applied to deduce the fuzzy quadratic appraisement method of site types, fuzzy vector and fuzzy characteristic period of site types is put forward, which achieves continuum of site types partition. Based on the collected datum of site types, the geo-model is constructed, which makes fuzzy isolines of site types and characteristic period available. In comparison with real datum measured, the site types by this fuzzy isoline is consistent with site types defined by "Code for seismic design of buildings", and fuzzy characteristic period are consistent with the period from the code very well, which justifies the significance of fuzzy isoline to seismic construction design.
