| 摘 要： | 文中对重塑的粉土试样施加正弦波和任意波轴向荷载,进行应变控制的动三轴试验。根据试验结果,分析和比较2种不同波形振动荷载下粉土的动强度和变形特性。研究结果表明:固结条件相同,振动频率为1Hz,任意波振动荷载作用下粉土的动强度较正弦波下的稍小;任意波下粉土试样产生的动应变比正弦波下的大。

| Abstract: | By setting axial load of sine and arbitrary waves on the remodeling silt samples,strain-controlled dynamic triaxial tests are conducted to study the dynamic strength and strain of the silt under vibrating loads with two different waveforms.The test results indicate that in the case of the same consolidation conditions and the vibration frequency of 1 Hz,the dynamic strength of silt under arbitrary wave is smaller than that under sine wave,and the dynamic strain of silt under arbitrary wave is contrary to th... |
