本文针对大连东港地区某工程的淤泥质粉质黏土进行电化学改性加固试验,阐述了电化学改性加固机理,提出了电化学改性加固实际加固区的计算公式和电化学能耗计算公式;最后通过轻便触探试验N10结果,表明电化学改性加固后,淤泥质粉质黏土的承载力特征值得到了大幅提高,龄期达到21d时,土体承载力特征值相比于加固前平均提高160%。试验结果表明淤泥质粉质黏土的化学改性加固试验具有良好的试验效果,改性加固后的淤泥质粉质黏土承载力提高幅度较大,满足工程需要。
In this paper, an experiment on electrochemical modification and reinforcement of silty silty clay in a project in Donggang, Dalian was carried out. The mechanism of electrochemical modification and reinforcement was discussed. The formula for calculating the actual reinforcement zone and the calculation formula of electrochemical energy consumption ; Finally, the result of the light touch test N10 shows that after the electrochemical modification, the characteristic value of the silt-bearing silty clay has been greatly improved. When the age reaches 21d, the characteristic value of the soil bearing capacity is lower than that before reinforcement Increase by 160%. The test results show that the chemical modification and consolidation test of silty silty clay has good test results. The bearing capacity of silty silty clay after modification and modification is greatly increased, which meets the needs of engineering.
