摘要
基于SIGMA模型,采用室内试验方法对土体强度的改良进行了研究,将石灰、粉煤灰、土体以及含水量加以不同的配比,从而形成复合地质体,通过对5种不同灰土比的模拟分析,计算出回填土的沉降值最小的优化组合,即粘土∶石灰∶粉煤灰为7∶1∶2,并与室内试验值对比,验证了模拟计算的结果具有很高的可信度。
Based on the SIGMA model, the paper adopts the indoor experiment method to research the improvement of the soil strength, has lime, coal ash, soil and water content with different proportion ratios, calculates the optimal composite of clay, lime and coal ash with proportion of 7: 1:2 with the minimal settlement value of the backfill soil with simulation analysis the five lime-soil ratios, and proves the results of the simulation calculation has the highest reliability.
