摘要:
液化震害调查是检验现有抗液化理论和方法的根本途径,而目前液化现场调查缺少指导性标准及定量化研究。本文根据汶川地震现场调查数据并参考以往地震液化调查数据资料,提出了宏观液化指数和宏观液化等级的概念,并建立了宏观液化指数和等级的评定标准。通过此评定标准给出了汶川地震液化点的宏观液化指数和等级,并综合评定了汶川地震主要液化区的宏观液化等级,即绵阳地区宏观液化等级为Ⅲ级,即中等;德阳地区宏观液化等级主要为Ⅲ级-Ⅳ级,即中等-严重;成都地区液化震害等级主要为Ⅱ级-Ⅲ级,即轻微-中等。本文建立的宏观液化指数及等级标准为宏观液化调查的定量化研究开辟了途径,但形成规范性标准尚需进一步深入研究。
Abstract:
Liquefaction in-situ investigation is the basic way to test existing anti-liquefaction theories and techniques. However, there is no guidance for post-seismic liquefaction investigation and relevant liquefaction quantitative studies at present stage. Using the liquefaction investigation data by Wenchuan earthquake and the documents of previous liquefaction investigation, macro liquefaction index and macro Ⅰiquefaction classes are proposed in this paper, and also the quantitative assessing criteria are given. By the criteria, the macro liquefaction indexes and macro liquefaction classes of the liquefied sites in Wenchuan earthquake are presented. Meanwhile, the macro liquefaction classes of the liquefied regions are determined, in which Deyang region is classified as Ⅲ to Ⅳ; Mianyang region is classified as Ⅲ and Chengdu region is classified as Ⅱ to Ⅲ. The concepts and criteria established herein pave the path for quantitative analysis of in-situ liquefaction investigation and provide operational procedures guiding post-seismic liquefaction investigation.
