| 摘 要： | 慢速往复荷载作用下土变形特性的研究不多见 ,但实际工程中土受到慢速往复荷载作用的例子很多。本文在先进的GDS应力路径三轴仪上对饱和砂土进行等围压不同周期的慢速往复荷载排水三轴试验。根据试验结果分析了饱和砂土在慢速往复荷载下的应力应变特性 ,并对饱和砂土的新特性 -卸载体缩特性进行了探讨 ,得到一些有益的结论

| Abstract: | Study on deformation behaviours of soil under slow reciprocating loading is not often seen but in practical engineering there are many examples of such case.Consolidated drained triaxial tests are conducted for the saturated sand under slow reciprocating loading by the advanced GDS stress path triaxial apparatus. The stress|strain properties of saturated sand under slow reciprocating loading are analyzed and the volumetric contraction after unloading is explored based on test results. Some useful conclusions are achieved. |
