| Popis: | 97 The cyclic strength of compacted soil is very different from ordinary sandy soil. In order to study the dynamic strength of compacted soil, this paper performed a series of dynamic triaxial tests on three kinds of compacted soils, SM, ML and CL for constructing an earth dam. This paper proposed a vacuum method for improving the saturation of compacted soils. Test results showed that both methods make the Skempton’s coefficient B of all specimens greater than 0.95. Compacted soils of the earth dam have different initial shear stress conditions which range from Kc=1.5 to Kc=2.0. Based on the test results, the higher initial shear stress ratio, the larger the dynamic strength and the less the pore water pressure. Dynamic strength of compacted soil is stronger than ordinary medium dense sand. Compacted soils have no liquefaction potential due to their shear dilation behavior and only sustain limited cyclic strain. |
