1、摘要二灰土阑其巢有强度较高、水稳健较好和裔利于环保等优点,在目前的麓等缴公籍惑藻攥中广泛使羽。餐怒对予二灰稳定褥殊±(麴膨胀主)的磷究并不系统和全嚣。本论文采震正交试验设计方法,戮不瓣龄期的无侧限摅爨强瘦弱7天于缕为考核搔撂,在黧内对二灰稳定膨胀±的配合毖逆行了研究,势依据二获±强度鞠千缵麴形成规理,疆及数璎统诗分毒嚣方法,愁试验结果进行了分析研究。嗣时,通过室内于湿法盎实试验,对:灰稳定膨胀土的碾嚣凄量掇制橡准进彳予了研究,著结合宁淮麓速公路二获稳定膨胀±的施工实践,总结了二灰土质量控制的荧键问题。研究表碉:影响二获±晕期强瘦的蓠要因索怒=灰院,影响二灰土黯期强度
2、的首要因索建二灰禽量。因此,在混合料组成设计时,应以较长龄期的试验维采必依据。二灰稳定膨胀±鹩台琏石灰含量约为8%~12%,二获跷黻l:3为佳。二灰稳定膨胀土应戬漱法击实试验获静的最大干密度和最佳含水鲎{乍毙矮蓬接制标准。本论文豹结论对令嚣遴一步并震二获稳定鬻藏±的磷究帮应蔫舆有~定懿建论徐僵及拯警{乍耀。荧键诩:二获稳定膨胀主:抗压强度;干燥收缡;于湿法;质量控制TheMixDesignMethodandApplicationStudyonLime—AshStabilizedExpansiveSoilABSTRACTBecauSeofmanymerits,such
