黄土高原渠系工程在建设运营过程中存在较大风险,而高分子材料与传统固化剂组合应用到黄土改良加固中,有着较广阔的发展前景.选用新型固化材料SH与石灰组合改良黄土,采用正交试验,测试其无侧限抗压强度;采用极差和方差,对试验进行综合分析.结果表明,10%掺量的SH和4%掺量的石灰是最优组合,养护时间为28d.研究结果可为探讨改良黄土的力学特性提供参考与借鉴.
At present,polymeric solidified materials combined the traditional ones will have wide prospect applied in the loess improvement areas.In this paper,the unconfined compression strength for new eco-material of SH combined lime to improve loess was designed using the orthogonal experiment method.Test results show that the optimal combination is 10%SH and 4%lime,and the air dried time is 28 days.The result possesses certain reference value for further engineering properties research on improved loess.
