The cyclic numbers increased with the higher frequency to reach the same peak dynamic pore pressure and dynamic strain ratio for given load amplitude. The dynamic strength index valueφincreased with the increasing vibration frequency also.
试验结果表明:饱和中砂动强度随振动频率增大而增大;给定荷载幅值,达到同一水平的峰值动孔压及动应变,频率越大所需要的振次越多;动强度指标φ值随振动频率的增大也有所增大。
