该文在某核电厂可研及设计阶段的场地地震液化判别分析中,比较全面的考虑了多种因素的影响,包括地下水位埋深的选取,采用不同的规范不同判别方法进行计算,对计算结果进行统计分析,按不同规范计算结果进行比较及按剪切波速法进行核实等。在经过以上步骤后得到了更科学合理的地震液化判别结论,可有效的指导设计人员进行设计。通过几种方法的统计、分析和评价,经过相互论证,得到了最终结论:按《核电厂岩土工程勘察规范》(GB51041-2014)计算的结果要比按《水利水电工程地质勘察规范》(GB50287-2008)计算的结果稍偏于安全。
In this paper, the field seismic liquefaction discriminant analysis of a nuclear power plant in feasibility and design stage has comprehensively considered the influence of many factors, including the selection of the groundwater table depth, the calculation by different criteria and different discriminating methods, The results of statistical analysis, calculated according to different specifications to compare and according to shear wave velocity method to verify. After the above steps have been more scientific and reasonable conclusions of the seismic liquefaction can effectively guide the design staff to design. Through the statistics, analysis and evaluation of several methods, through mutual argumentation, the final conclusion is obtained: the results calculated according to the “Geotechnical Investigation Standards of Nuclear Power Plant” (GB51041-2014) are better than those calculated according to “Rules for Geological Prospecting of Hydroelectric Engineering” GB50287-2008) calculated slightly biased in safety.
