PROPERTIES OF COMPACTED SOILS UNDER TRANSIENT LOADS

摘要

References(2) This paper presents results of tests made to determine the mechanical properties of compacted soils under transient loads. The tests were made on soils of three types, clay, loam and sandy loam of various moisture contents and compacted densities. Increase in the ultimate strength of compacted soils was observed as the loading rate increased, that is so-called strain-rate effect, but there also were such cases that the ultimate strength in the normal static tests was higher than that in the transient load tests, according to soil types or conditions of moisture content. The changes in modulus of deformation and the effects of compacted densities on the ultimate strength are also presented.
