固化风沙土强度试验研究

摘要

对取自内蒙古高原鄂尔多斯库布其沙漠中的风沙土样进行了固化强度方面的研究,分别进行了筛分、击实、无侧限抗压等试验.试验的结果表明:在风沙土中加入固化剂后,试件抗压强度随固化剂掺量的增加,先增加后减小；随着龄期的增加,抗压强度的逐渐增加；加纤维试件与未加纤维的试件相比,后期强度增加的比较快,增加的幅度较大.通过两种情况下的抗压试验结果,得出固化剂的最佳配合掺量为10％.%It takes research on the solidify intensity of windy sand samples taken from the Ordos Kubuqi desert located in the Inner Mongolian Plateau, including screening, compaction and unconfined compression intensity test. Test results show that solidify Boil with fiber, compressive strength is enhanced with the increasement of the curing agent content and its amplitude is also enhanced especially in the late period comparing with the soil without fiber. Throughout the serious of tests, it can be obtained that curing agent content of 10% is the best proportion or the best results.
