Indoor Experimental Study on Improvement Technology for Overwet Soil in Ya'an Region

WU Jiu-jiang1,WEN Hua2,CHENG Qian-gong1(1.School of Geological Science and Environmental Engineering,Southwest Jiaotong University,Chengdu 610031,China; 2.School of Civil Engineering and Architecture,Southwest University of Science and Technology,Mianyang 621010,Sichuan,China)  
Through large amount of indoor tests and against the overwet soil in Ya'an Region mixing lime,cement and EN-1 soil stabilizer,the laws relating to loss of moisture content and change of engineering mechanical properties are studied;the engineering properties of various improved soil and the relationship between various factors such as additive content,moisture content and age of plain soil,is analyzed;and the technical parameters of the improved soil are compared.The test results show that the effect of improvement by mixing cement is superior to that by mixing lime and the improvement effect with new EN-1 stabilizer together is more outstanding.
