交联生物聚合物增强红黏土物理力学性能研究
Study on the physical and mechanical properties of red clay enhanced by cross-linked biopolymers
摘要
Abstract
To improve the strength and stability of red clay and address the environmental pollution and durability issues associated with traditional soil stabilization methods,γ-polyglutamic acid(γ-PGA),β-glucan,and their cross linked polymer γ-PGA-β-G were used to modify red clay.The optimal ratio of γ-PGA-β-G was determined using response surface methodology,and the effect of cross-linked biopolymers on the physical and mechanical properties of red clay was investigated.The results indicate that γ-PGA-β-G outperforms single biopolymers in terms of reinforcement.At a γ-PGA-β-G content of 2.5%,the reinforcement effect on red clay was optimal.Compared to untreated red clay,the unconfined compressive strength,cohesion,and internal friction angle increased by 74%,47.06%,and 41.68%,respectively,and the compression modulus decreased by 54.81%.The γ-PGA-β-G cross-linked matrix effectively fills the gaps between soil particles and binds the particles into a cohesive mass,significantly enhancing the mechanical properties of red clay.This study provides a novel environmentally friendly soil stabilization solution for infrastructure construction in southern red clay regions.关键词
