砂土液化现象是地震灾害的表现形式,通常会引起建筑地下基础的不均匀沉降及结构的破坏,还会造成人员伤亡和自然灾害。因此对砂土液化的研究有着十分重要的现实意义,并为实际的建筑工程中砂土液化的防治提供一些理论依据与评价标准。在查阅大量资料的基础上,叙述了砂土的概念及分析砂土在地震作用下的砂土液化机理及砂土液化的一些影响因素,并对其判别方法进行了分析,提出了对砂土液化判别的方法研究的展望。
Sand liquefaction is a form of earthquake disaster. It usually causes uneven settlement and structural damage of the underground foundation of the building, as well as casualties and natural disasters. Therefore, the research on liquefaction of sand has very important practical significance and provides some theoretical basis and evaluation criteria for the prevention and treatment of sand liquefaction in the actual construction project. On the basis of consulting a large amount of data, the paper introduces the concept of sand and analyzes the sand liquefaction mechanism of sandy soil under earthquake action and some influencing factors of sand liquefaction, and analyzes its discriminating method. Prospect of the Method of Liquefaction Judgment.
