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.
The Investigation of Compressive Strength Testing for Modified Loess
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.
