本文从仪器设备、操作方法、贯入机理和影响因素等多方面说明用静力触探法来评价饱和砂土地震液化可能性,比我国现行《工业与民用建筑抗震设计规范》采用的标准贯入试验法更加快速、简便和经济,且其成果也更准确和稳定。轻型链式电测十字板—触探两用仪,由于轻便灵活、操作简单和不用交流电源等特点而适合于用来在地震区大量作这类试验。
In this paper, static penetration testing method is used to evaluate the possibility of seismic liquefaction of saturated sandy soil from many aspects such as equipment, operation methods, penetration mechanism, and influencing factors, which is more than the standard adopted by China’s current “Code for Seismic Design of Industrial and Civil Buildings”. Into the test method is more rapid, simple and economical, and its results are more accurate and stable. Light chain type electrical test cross-cone probe dual-purpose instrument, due to the characteristics of light and flexible, easy to operate and not using AC power, is suitable for a large number of such experiments in the seismic zone.
