摘　　要：通过制备五组不同生物酶掺量的淤泥土试样进行一系列室内试验来探究生物酶改良淤泥土的液塑限、抗剪强度、最佳含水率以及最大干密度的变化规律,并对素土和改良土的各项基本物理力学性质进行比较分析。研究表明:在掺量为6%时,淤泥土的改良效果最明显,并且强度最高。Through the preparation of five groups of silt soil samples with different bio-enzyme contents and a series of indoor tests,the variation laws of liquid-plastic limit,shear strength,optimal moisture content and maximum dry density of the bio-enzyme modified silt soil are explored,and the basic physical and mechanical properties of the plain soil and the modified soil are compared and analyzed.The research shows that when the dosage is 6%,the silt soil has the most obvious improvement effect and the highest strength.
