Application Study Of Prevention Technology Aboutsuffusion Deformations Of Saline And Frost-heave Disease In Highway Of The Xinjiang Bingtuan Reclamation Area

Based on the collections existing results of suffusion deformations of saline and frost-heave in abroad and home, pass the investigation--analysis studying,putting forward initial method of solving problem--trial(outside and indoor)--practice, got the characteristic and law of suffusion deformations ofsaline and frost-heave disease in Xinjiang Bing-tuan reclamation area highway; Accoding to the laws, putting forward the economy-suitable engineering measure of Bing-tuan reclamation area highway disease, and through the engineering practice has been certificated, for the highway design and construction provided the basis of the seasonal frozen Salinized Soil district in the bing-tuan reclamation area,it is for the corresponding standard has perfectly established the foundation.(1)Research on evaluation of suffusion deformations of saline and frost-heave,and characteristic and regulation in Xinjiang Bing-tuan reclamation area;(2)Pass the inquisition of Bing-tuan reclamation area highway,experiment road to construct and experiment result, influence factor combine the environment of build road, system of analytical study the reasonand its mechanism,prevented method about the suffusion deformations of saline soil and frost-heave delivers,and its comprehensive disease in Xinjiang Bing-tuan reclamation area highway.(3)First Put forward the stop temperature is 2℃of suffusion deformations of saline soil about sulphate salty and subsystem the transform stage and temperature zone about and frost-heave disease,the suffusion deformations of saline soil stage,the suffusion deformations of saline soil and frost-heave delivers stage,the frost-heave stage.(4) Subsystly research on the possibility of prevented the suffusion deformations of saline soil and frost-heave disease use eolian-sand from the grain constitute,chemistry characteristic,mechanics properties of eolian-sand,put forword the apply condition and scope,minimum thickness and construction request etc of eolian-sand separation layer to prevent and cure suffusion deformations of saline soil and frost-heave delivers.(5) Pass trial engineering and inquisition road analytical, system study the apply condition and scope and construction request ofgeosythetics separation layer,lower roadbed water level method and strengthens the road noodles structure method and synthesizes measure to prevented and cured the suffusion deformations of saline soil and frost-heave disease.
