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

摘要：

　　General triaxial CD and CU tests are conducted to properly understand mechanicalproperty 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.
