摘　　要：天然植物纤维普遍具有一定的抗拉性能,可以作为土木工程土体改良的重要材料。为分析天然植物纤维对土木工程土体改良的具体效果,以稻草秸秆纤维为例对粉质土木工程黏土进行了增强改性,以实验方式对增强改性后的粉质黏土力学特性进行分析。结果表明,经过天然稻草秸秆增强后,粉质黏土的抗压强度、抗剪强度、水稳定性均获得一定提升。随着养护时间的延长,这种性能的提升效果越来越明显,当养护时间超过28d后,性能提升逐渐停止。Natural plant fiber generally has certain tensile properties,and can be used as an important material for soil improvement in civil engineering.In order to analyze the concrete effect of natural plant fiber on soil improvement in civil engineering,the silty clay was reinforced with straw straw fiber as an example,and the mechanical properties of the reinforced silty clay were analyzed experimentally.The results showed that the compressive strength,shear strength and water stability of silty clay were improved after the natural straw straw was strengthened.With the extension of curing time,the improvement effect became more and more obvious.When the curing time exceeded 28d,the performance improvement gradually stopped.
