Liquefied Soil Seismic Damage Analysis And Analytic Hierarchy Process(ahp) In The Application Of Liquefaction Resistance Selection Research

A lot of theory and practice,and many facts have proved for the saturated sand or silt,less cohesive soil of foundation soil,in periodic load under the action of an earthquake or other dynamic loads it is easy to produce liquefaction phenomenon,cause failure of foundation,buildings or other destructive ground facilities,caused great economic losses to the people.Caused by seismic soil liquefaction is a regional,in the event of the building of modern city devastating;It is directly related to people's life and property safety,the study of soil liquefaction phenomena and liquefied foundation treatment method is very necessary.Under the action of earthquake load,there are many reasons for the liquefaction of saturated soil.The main factors are the composition and density of the soil,the thickness of the non liquefied soil layer,the depth of the groundwater level and so on.Determine the liquefaction degree and damage of soil and the measures to prevent and cure the soil by using the judgment of liquefied soil.At present,there are a lot of methods to deal with the liquefaction process.In the selection of the optimization method,not only the construction units have reliable technical construction level,but also the impact of urban construction planning and social environment(including production,living environment and ecological environment),and finally achieved good economic benefits.In this way,the selection of the treatment scheme of the liquefied foundation is simple and effective by using the analytic hierarchy process.The feasibility of the method is illustrated by a practical engineering example,which can avoid the loss caused by the personal decision making.
