摘要

为解决松嫩平原碳酸盐渍土对工程的不利影响,且削弱季节冻土区冻融循环对碳酸盐渍土带来的损伤,采用无机材料石灰和粉煤灰对碳酸盐渍土进行改良。研究了不同改良方案下碳酸盐渍土抗剪强度的变化及其抵抗冻融循环的能力;通过熵权-TOPSIS模型对各改良方案进行评价。结果表明:石灰和粉煤灰均会提升碳酸盐渍土的抗剪强度,但是石灰的改良效果远胜于粉煤灰,石灰会使得碳酸盐渍土的应力-应变曲线变成应变软化型;粉煤灰在提升碳酸盐渍土抵抗冻融损伤能力上表现得比较突出;而双掺石灰和粉煤灰明显兼顾了强度和抵抗冻融损伤能力这2个指标;在考虑力学性能、抗冻融能力以及经济等因素时,石灰和粉煤灰的掺量均为12%的方案最优。

Abstract

The aim of this study is to mitigate the adverse impacts of saline-carbonated soils in the Songhua River and Nenjiang River Plain on engineering and to weaken the damage caused by freeze-thaw cycles on saline-alkali soils in regions of seasonally frozen ground by using lime and fly ash to solidify saline-carbonated soils.The study investigates the effect of different improvement schemes on the shear strength of saline-carbonated soils and their ability to withstand freeze-thaw cycles.The solidification schemes are evaluated using the entropy-weighted TOPSIS model.Results indicate that both lime and fly ash have enhanced the shear strength of saline-carbonated soils.However, the solidification effect of lime is significantly superior to that of fly ash and has transformed the stress-strain curve of saline-carbonated soils into one with strain-softening behavior.Fly ash has distinguished performance in enhancing the resistance of saline-carbonated soils to freeze-thaw damage.The admixture of both lime and fly ash comprehensively accounts for shear strength and resistance to freeze-thaw damage.From the perspective of mechanical properties, freeze-thaw resistance, and economic factors, the optimal solution is the use of 12% lime and 12% fly ash.
