Abstract高分子材料在土加固工程中有很大的发展前途。SH为新型水溶性高分子固化材料。通过单轴抗压强度试验、X射线衍射、红外光谱、扫描电镜结合X射线电子能谱及比表面/微孔隙分析等现代测试手段,研究了SH加固黄土的强度特征,探讨该固化材料的固化机理。结果表明:SH加固黄土的强度随着SH掺量的增大而增加,但不是线性关系;SH固化黄土的后期强度很高。黄土用SH固化后,压缩性减小,湿陷性消失。SH的掺入,改变了黄土的结构,使黄土的颗粒间联结增强。它通过氢键、离子交换、吸附、絮凝等物理化学作用于黄土而显著提高黄土的强度。
Other AbstractPolymer materials have wide prospect of application to soil solidification engineering. SH is a new water-soluble solidification material. Based on the uniaxial compressive strength test, and modern analysis methods such as X-ray diffraction (XRD), Fourier transform infra-red (FTIR), scanning electron microscope, X-ray energy dispersive spectrum (EDS) and surface area/micro porosity, the mechanism and strength characteristics of the SH solidified loess are analyzed. The research results show that the strength of the solidified loess increases with the content of SH, but the interrelationship is not linear, and long-term strength of solidified loess is very high. After loess is solidified by SH, the compressibility decreases, and the collapsibility is lost. The admixing of the SH changes the structure of the loess. It makes the connection of loess grains stronger. By hydrogen bond, ion exchange, absorption of macromolecular and flocculation; the physicochemical interaction may occur between SH and the loess. This may be the main reason for the improvement of the strength of the loess.
