论工程地质工作中的地震液化评价

地震液化对建筑物带来危害极大,因此做好地震液化评价工作,防止液化危害具有重要意义.地震液化评价工作包括初判、复判和液化等级判定三个步骤.目前最常用、最方便的为标准贯入击数法.为了更准确地评价地震液化,提出了在勘察工作中应注意的几个问题,并介绍了液化评价及处理的工程实例.

Evaluation on seismic liquefaction in geological survey

Seismic liquefaction is extremely harmful to the engineering structures. The evaluation on seismic liquefaction plays an important role in preventing liquefaction disaster. Generally, seismic liquefaction evaluation involves three steps: - initial estimation, secondary estimation and determination of liquefaction degree. At present, a convenient method, namely the standard punch test, is widely used. For the purpose of accurate evaluation on seismic liquefaction, several issues that should be paid attention to in geological exploration are discussed in this paper. Also an example in determination and processing of liquefaction is introduced.
