岸坡土体物化改性下干湿、冻融交替力学试验研究

Experimental study on alternate mechanics of dry,wet and freeze-thaw under physicochemical modification of bank slope soil

为了研究佛山东平河联圩工程堤防岸坡改性土力学特征,开展石灰、类米浆剂两种改性剂的改良效果力学试验,分析改性土与原状土力学特性与抗剪强度特征。从堤防岸坡土体改良设计考虑,石灰作为更适配的物化改性剂,为研究物化改性土体方法及改性力学试验提供参考。

In order to study the mechanical characteristics of modified soil on the embankment slope of foshan City Dongping River Lianwei project,the mechanical tests on the improvement effect of lime and rice slurry like agent were designed and carried out,and the mechanical characteristics and shear strength characteristics of modified soil and undisturbed soil were analyzed.Considering the soil improvement design of embankment bank slope,lime is a more suitable physicochemical modifier.This paper can provide a reference for the study of physicochemical modified soil method and modified mechanical test.
