摘要
文中依托某垃圾填埋场三轴水泥土防渗墙检测项目,对水泥土搅拌桩防渗墙进行渗透性能、完整性及抗压强度检测,并对试验结果进行分析总结.结果表明,水泥土防渗墙渗透系数均小于10-6 cm/s,完整性为Ⅰ～Ⅱ类,但桩身下部水泥土的抗压强度未满足设计要求.综合而言,其基本可以满足垃圾填埋场防渗墙的抗渗要求.
Abstract
Based on the triaxial cement-soil anti-seepage wall testing project of a certain landfill,the permeability,integrity,and compressive strength of the cement-soil mixing pile anti-seepage wall were tested,and the test results were analyzed and summarized.The results show that:The permeability coefficient of the cement-soil anti-seepage wall is less than 10-6cm/s,and its integrity is Class I～II.However,the compressive strength of the cement-soil below the pile body does not meet the design requirements.Overall,it can basically meet the impermeability requirements of the anti-seepage wall of the landfill site.
