摘要
通过试验测试,建立连云港海相软土电阻率结构模型,并尝试应用此模型来定量分析软土蠕变过程中的微结构变化规律,运用所测得的软土电阻率参数预估软土蠕变量。通过电阻率测试结果,研究并推导出海相软土受荷时的蠕变与其微结构之间的内在相关式,并运用电阻率结构综合因子M较好预估蠕变量。将电阻率结构模型理论引入到软土的微结构量化研究,将从根本上克服传统的土结构性研究方法的弊端,大大提高土结构指标测试的可操作性和一致性,为定量描述受荷时软土蠕变过程中的微结构变化规律、预估软土蠕变提供一种新途径、新方法。
Based on the test measurement, the electrical resistivity model of Lianyungang marine soft soil is established; and this model is applied to illustrate the change rule of microstructure of Lianyungang marine soft soil during creep. Furthermore, the soft soil creep value is estimated by the means of electrical resistivity indices. And then, the correlation between the microstructure and the creep is demonstrated; and the parameter M, integrative electrical resistivity structure factor, can well evaluate the creep value of marine soft soil. Applying the electrical resistivity model to study quantitatively the soft soil microstructure, this method will radically overcome some deficiencies of conventional microstructure method and greatly improve the operability and consistency of obtaining soil microstructure indices. Accordingly, a new method is presented to illuminate the change rule of microstructure of marine soft soil during creep and to estimate the creep of soft soil.
