为研究玻璃纤维加筋水泥土的效果,开展无侧限抗压强度试验。分别研究纤维掺量和纤维长度对纤维加筋水泥土无侧限抗压强度的影响。研究结果表明:纤维的加入能提高水泥土的延性,改善水泥土的脆性,极大的提高水泥土的残余强度;同时纤维能有效提高水泥土的无侧限抗压强度,纤维水泥土的强度受纤维掺量影响较大,最优纤维掺量为2‰;纤维掺量一定时,当纤维长度为9 mm时,纤维的加筋效果最佳。
In order to study the effect of glass fiber reinforced cement soil, a unconfined compressive strength test was carried out. The effects of fiber content and fiber length on the unconfined compressive strength of fiber-reinforced cemented soil were studied. The results show that: the addition of fiber can improve the ductility of cement soil, improve the brittleness of cement soil, greatly improve the residual strength of cement soil; at the same time, the fiber can effectively improve the unconfined compressive strength of cement soil, the strength of fiber cement soil Affected by the fiber content, the optimum fiber content is 2 ‰. When the fiber content is constant, the fiber reinforcement effect is the best when the fiber length is 9 mm.
