The Digital Analysis of Soil Experiment Using CT

Pn Yibin;Wu Ziwang;Chang Xtaoxiao; Liao Quanrong(State Keg Laboratory of Frozen Soil Engineering,LIGG, AS)  
As a system of more composition and dispersed phase,since existence ofrock and ice, the thermal and mechanical properties of frozen soil become quite compliCated.Under the certain condition,the change of internal composition and structure is basis data onstudy of frozen soil.Through transforming of technique,the medical CT is applied in test offrozen soils.Thus it is achieved for both continuous undamaged measurement and quantitativedescription of internal structure change of sample under different experimental conditions.Meanwhile,we also can obtain directly the quantitative picture of different layers.For continuously dynamic measurement,a special experdriental device matched with CT isdeveloped. Using this device,sample may be applied pressure uniaxial and triaxial stress condi conditions and can keep the temperature precision of less than ± 0. 5°in environment of 0- 30℃.Temperature and pressure may change with requirement of tests.Through scanning and mea suring of several hundreds of samples which have different shape,dry density and water con terrt, we have obtused quantitative relation among CT value,shape, dry density and watercontent. Based on this relation, we may analyse quantitatively change of sample under differ ent conditinns of test.Through a large number of scanning of Lanzhou loess,the numericaleveluation which connected soil parameter and CT data have been created.It is found that the strengthening and softening action of structure of frozen soil are con trolled by growing microcracks,being broken particle aggtegates and extending structuraldamage in creep process,as well as the form characteristics of creep process. Since actinn ofshear stress,the damage of ftozen soil firstly occurs in the centre of sample, then spread to wards outside and last results in damage of whole structure.
