Experimental Study on Strength Characteristics of Cement-Soil under CD/CU Condition

Abstract:

Article Preview

General triaxial CD and CU tests are conducted to properly understand mechanical property of cement-soil. Experiment data indicate that: (a) different stress paths have some but little influence on the strength of cement-soil; (b) under low confining pressure, cement-soil is similar to highly overconsolidated soil with shear dilatancy property; but under high confining pressure, it is similar to slightly overconsolidated soil; (c) its residual strength increases linearly with the increase of confining pressure, and the residual strength of CD test is greater than that of the CU test; (d) the ratio of residual strength to peak strength increases with the increase of confining pressure, while its increasing rate decreases; (e) the effective stress envelope of CU test and that of CD test are basically identical.
