Study On The Liquid And Plastic Limit Of The Loess Layers

The depth of the loess deposition thickness， length of time， crowns the world.Xian Renslope loess section is complete， significantly different times stratigraphic division， loesslayer changes with the red paleosol layers alternating regularity， domestic and foreignscholars have done a lot of sampling of it. Ren slope loess section through a lot of siteinvestigation sampling， proposed a new stratigraphic division and layers of loess nature of adetailed description.Soil of liquid and plastic limit is an important indicator of the division of soil type andevaluation of engineering properties of soil， Accurately determine the soil solution plasticityindex， the design and construction of the project is of great significance. Due to nature of theworks the past， liquid and plastic limit sample dispersion， limited to simple dataengineering determination， the variation of the whole profile of the liquid and plastic limitextension of the lack of the necessary research. In this paper， the number of explicit jointlydetector， combined with the new stratigraphic division Liu slope loess section in differentlayers liquid and plastic limit test determination， aims to identify the liquid and plastic limitof the variation in the vertical extension of the loess section. Lot of information to identify theliquid and plastic limits of the influencing factors and these factors affect the extended profilevertical variation analysis， further from the theoretically derived from the test liquid plasticlimit changes in the law to be demonstrated.The Macrofunction provide important indicators for the division of fine grained soil， animportant indicator of the detection of clay， loess， and bearing capacity of foundation.Application of liquid and plastic limit combined detector a large number of tests， the jointwas determined by measuring soil liquid and plastic limit the problems and improvements.
