摘要
通过劈裂抗拉试验,研究纤维掺量、水泥掺量、土样含水率和养护龄期等4个主要因素对纤维水泥土劈裂抗拉强度的影响。研究结果表明:纤维水泥土劈裂抗拉强度与纤维掺量、水泥掺量及养护龄期呈正相关关系,与土样含水率呈负相关关系;水泥土破坏模式为脆性破坏,纤维水泥土破坏模式为塑性破坏。
By split tensile test, the influence of fiber content, cement content and soil moisture content and curing age on the split tensile strength of fiber reinforced cement soil was studied. The results show that the split tensile strength of fiber reinforced cement soil is positively correlated with fiber content, cement content and curing age, and negatively correlated with soil moisture content. The failure mode of cement soil is brittle failure and the failure mode of fiber reinforced cement soil is plastic failure.
