摘要
就软土次固结系数的影响因素进行了分析,总结了应力水平、应力历史、加荷速率、应力比等因素对次固结系数的影响,以及次固结系数与压缩指数和塑性指数的关系等诸多方面的研究成果,以期对软弱土地区的高速公路地基工后沉降问题提供参考。
The following paper analyzes the factors influenced coefficient of secondary consolidation of soft soil, summarizes the influences of stress level, stress history, loading rate and stress ratio on coefficient of secondary consolidation, and illustrates several research results as the relationship among coefficient of secondary consolidation, compression index and plasticity index, in order to offer a reference for the settlement problem of expressway foundation after construction in soft soil region.
