Dynamic triaxial vibration test on geogrid reinforced clays were made under cyclic loading. Results show that the confining pressure, the dynamic stress amplitude, the reinforced geogrid layers and soil moisture content have obvious effect on the dynamic strength of the reinforced clays. For the effect of the dynamic stress amplitude and reinforced geogrid layers the essence is the differences dissipation of energy, while the confining pressure effects the dynamic strength of the geogrid reinforced clays by means of its own structure.%进行循环荷载作用下的土工格栅加筋粘性土的动强度影响因素的动力三轴试验研究,结果表明围压、动应力幅值、加筋层数对加筋土的动强度都有明显的影响.动应力幅值及加筋层数影响的实质是能量耗散不同,而围压是从加筋土本身结构方面影响加筋土的动态强度.
