胶结液浓度对微生物加固红黏土强度的影响研究
Effect of cementation solution concentration on the strength of microbially reinforced red clay
摘要
Abstract
Microbially Induced Carbonate Precipitation(MICP)technology was used to reinforce red clay.The influence of cementation solution concentration and the ratio of bacterial solution to cementation solution on the unconfined compressive strength of the reinforced soil was investigated through unconfined compressive strength tests.Additionally,the mechanism of MICP technology in reinforcing red clay was explored through microscopic analyses,including X-ray diffraction(XRD)and scanning electron microscopy(SEM).The results show that the compressive strength of the reinforced red clay was 30%to 100%higher than that of the control group.The compressive strength increased with the concentration of the cementation solution.Red clay with a bacterial solution to cementation solution ratio of 1∶2 exhibited higher compressive strength than that with a ratio of 1∶1.Microscopic analysis indicates that the main reason for the strength improvement is that calcite precipitated through microbial mineralization effectively fills soil pores and cements soil particles.关键词
