本文提出了地下工程场地非均质地基液化综合判别方法,介绍了该方法的判别程序、过程,对影响液化判别结果的诸因素进行了较深入分析,并将该方法成功地应用于上海市地铁2号线一期工程详勘中,实践证明基于宏观定性判别——原位、室内试验定量计算——定性定量综合分析的综合判别方法是合理有效的。
This paper presents a comprehensive method for the identification of heterogeneous liquefaction in underground engineering sites. The identification procedures and procedures of this method are introduced. The factors that influence the liquefaction discrimination results are analyzed in depth. This method has been successfully applied to Shanghai Metro. In the detailed survey of the first phase of the No. 2 line, the practice proved that the comprehensive discriminating method based on qualitative and quantitative discrimination—in-situ and in-house experiment quantitative calculation—quantitative and qualitative comprehensive analysis is reasonable and effective.
