摘　　要：在内蒙古中部地区的生土中引入莜麦秸秆和羊毛纤维进行改性生土试件抗压强度提升的试验,试验中使用当地易于获取的天然土壤、莜麦秸秆和羊毛,经人工压实制坯,再进行抗压强度试验。试验数据表明,添加莜麦秸秆可将改性生土试件强度提高40.5%,添加羊毛纤维可将强度提高89.25%,此外,试验也揭示了改性生土试件抗压强度顺应两种纤维材料的变化规律,并确定了最佳纤维含量。In this study,an experiment was conducted for enhancing the compressive strength of compression-stabilized earth blocks(CSEBs)by introducing oat straw and wool fibers in raw earth in the central region of Inner Mongolia.Here,natural mud,oat straw,and wool are readily available locally.These were used to make CSEBs through manual compaction,and then,compressive strength experiments were conducted.Adding oat straw and wool fiber increased compression strength by 40.5%and 89.4%,respectively.The relationship between the content of two types of fiber materials and the compressive strength of CSEB was also demonstrated,and the optimal fiber content was determined.
