基于实测沉降时间过程的双曲线模式和一维太沙基固结理论 ,推导了在等载条件下的沉降速率计算式 ,提出了高速公路路基预压期沉降速度控制标准。在此基础上 ,讨论了超载条件下 ,沉降速率控制标准的修正 ,并给出了沉降速率放大系数 Based on the hyperbolic model and the one-dimensional terbutary consolidation theory, the settlement rate under equivalent load conditions was deduced and the settlement control standard for subgrade preloading was proposed. On this basis, the correction of settlement rate control standard under overloading condition is discussed, and the settlement rate amplification coefficient
