    摘要:

    为合理利用废弃材料改善生土材料力学性能,通过在素土中掺入糯米浆、废玻璃渣和橡胶,形成改性土体材料,设计5种配合比方案,制作Φ102 mm×116 mm圆柱体试块。通过对其进行轴心抗压强度试验,对比不同配比试件的试验现象、抗压强度、变形能力、荷载位移曲线,分析不同掺合料的作用机理、研究不同掺料不同掺量对抗压强度的影响规律,提出了玻璃渣和橡胶掺量的合理范围。试验结果表明,在素土中掺入糯米浆能提高素土抗压强度,掺入糯米浆、玻璃渣和橡胶,可提高抗压强度和变形能力,但其抗压强度随玻璃渣和橡胶掺量的增多增至3.12 MPa后下降。

    Abstract:

    Some glutinous rice pulp, waste glass slag and rubber are added into plain soil to form modified soil material for the rational use of waste materials to improve the mechanical properties of raw soil material. According to the five kinds of mix proportion scheme, the size in diameter 102mm with high 116mm cylinder specimens were prepared. Through the axial compressive strength test, the experimental phenomena, compressive strength, deformability, load-displacement curves of specimens with different proportions are compared, and the mechanisms of different admixtures are analyzed, and the influence laws of compressive strength with different admixtures and different amount are studied. The reasonable range of he mixing amount of glass slag and rubber is proposed. The results show that the compressive strength of the soil can be enhanced by the incorporation of glutinous rice pulp into the soil. With the incorporation of glutinous rice pulp, glass slag and rubber, the compressive strength and deformation capacity can be improved, but the compressive strength decreases after 3.12MPa with the increase of the amount of glass slag and rubber.
