针对目前执行的国家标准GB 50025-2004《湿陷性黄土地区建筑规范》源于工业与民用建筑行业经验,不能完全适用于机场工程建设需要的问题,提出了适合于机场工程黄土湿陷性评价的方法。文章根据对黄土基本湿陷特性的研究,结合机场工程的具体特点,从湿陷系数的测定压力、湿陷量的计算厚度、构造物类别的划分等方面对湿陷性黄土的评价进行了探讨,给出了机场工程中湿陷性黄土评价时湿陷性系数的测定压力、湿陷量计算厚度等的建议值。
According to the current implementation of the national standard GB 50025-2004 “collapsible loess area building code” from the industrial and civil construction industry experience, can not be fully applied to the airport construction needs of the issue, put forward for the loess collapsible airport evaluation Methods. Based on the study of the basic collapse characteristics of loess and the specific characteristics of the airport project, the paper evaluates the evaluation of collapsible loess from the measurement pressure of the collapse coefficient, the calculated thickness of the collapse quantity and the classification of the structure category , Gives the recommended values for determining the collapsibility coefficient of collapsible loess in the airport project and calculating the thickness of the collapsible slump.
