场地抗震性能评价的基本方法与有关问题

Basic methods for site aseismatic capability evaluation in geotechnical investigation and related problems

随着城市高层建筑和处于抗震不利地段的工业与民用建筑勘察工作日趋增加 ,以往勘察工作中涉及场地抗震性能的内容较少 ,场地抗震性能评价作为设计输入的作用应受到重视 ,有必要作为岩土工程勘察的一项重要组成内容。文章根据近几年来开展场地抗震性能评价工作的经验 ,综述了评价的基本方法和存在的主要问题。

Survey tasks of high rises and civil buildings sited on earthquake disadvantage areas is increasing considerably, but the contents of the site aseismatic capability are seldom involved in past survey tasks,This paper considers the site aseismatic capability evaluation as an important design input, and such evalution should be incorporated into rock and soil survey. Based on the experiences in the site aseismatic capability evaluation in recent years, this article gives a summary of the basic methods for the evaluation. Related problems are also discussed.
