【摘要】 拟建48座桥梁位于金堤河干流,是金堤河二期治理工程主要工程项目。饱和砂土震动液化是各桥基土主要工程地质问题之一,笔者根据各桥基土工程地质条件,分析研究场地的宏观液化势,用标贯、静探和动三轴试验方法进行地基土液化可能性判别,并对各桥基土进行液化危险性等级划分。更多还原

【Abstract】 The forty-eight bridges which will be built in main stream of Jindi River,is the major engineering projects of second stage regulation project of Jindi River.Seismic liquefaction of saturated sand is the major engineering geological problem of each bridge foundation soil.Based on engineering geological condition of each bridge foundation soil,the macro liquefaction potential analysis of site is performed,the liquefaction possibility of foundation soil is discriminated by using standard penetration,cone penetration test and dynamic triaxial test,the liquefaction risk grade of each bridge foundation soil is divided.更多还原
