摘要: 通过数字试验，分析了不同编图方法对地震区划结果的影响．基于四川及邻区的地震地质环境、地震活动特征、K2值特征、Delta;Tg分布特征，考虑到地震区划图的继承性和连续性以及与我国现行抗震设计规范的衔接，提出了抗倒塌地震区划图编制的编制原则和方法，编制了四川及邻区的抗倒塌地震区划图．

Abstract: This paper analyzed the influence of different zonation methods through a numerical experiment. By taking into consideration not only the inheritance and continuity of previous versions of seismic zonation maps but also the joint of updated seismic design provision, the authors propose a set of criteria and methodologies for compiling the seismic zonation maps against collapse of structures based on the features of geological background, seismicity, K2 value and Delta;Tg distribution in Sichuan and adjacent region. Then the seismic zonation maps against collapse of structures for Sichuan and adjacent regions has been compiled.
