摘要
随着经济的发展,延庆城市建设不断扩大,有必要对延庆卫星城规划区域范围开展岩土特性与地震液化关系的研究,以减轻地震灾害对城市建设的威胁。本文通过对70份延庆县城建设项目岩土工程勘察报告的筛选分析,搜集整理延庆县的地震和水文资料,结合国内外有关震例阐述了地震液化的因素,对延庆县城地区的岩土分布特性与地震液化的关系进行初步研究,得出了该地区大部分土层不会形成地震液化,只有局部地区存在发生地震液化的因素,应在城市建设中采取有效措施来保证工程安全。
Based on the selection and analysis to 70 geotechnical engineering construction project reports in Yanqing Country,this paper elaborates the factors of earthquake-induced liquefaction with relevant shock examples domestic and foreign,preliminarily studies the relationship between the soil distribution properties and earthquake-induced liquefaction in Yanqing Country,puts forward measures to prevent earthquake-induced liquefaction,and provides the reference frame to plan earthquake plots and manage the engineering of seismic protection.
