6、地震液化可很好的起到砂基预震效应,同时还可以起到排水降压作用。2.试验目的(1)通过试验结果确定有关施工技术参数和施工工艺;(2)通过砂石桩试验确定地层的加固效果;3.编制依据(1)《南水北调中线一期工程总干渠温博段、焦作1段渠道饱和砂土液化地基处理施工技术要求》(河南省水利勘测设计研究有限公司2009年9月)(2)《建筑地基处理技术规范》(JGJ79-2002);4.试验方案4.1设计技术要求(1)桩孔布置:采用等边三角形布置,桩中心距2.0m;(2)成孔直径≥500㎜;(3)可液化砂土处理后相对密度≥0.75,或标准贯入击数不低于地震液化临界标贯击数;(4)地基处理深度:砂石桩底部
7、高程▽96.22m;(5)成孔方式:沉管成孔,间隔(跳打)进行,并由外侧向中间推进;(6)处理范围:距渠道中心线两侧各38.0m范围内;(7)材料:砂石桩法桩体的填料含泥量不大于5%,最大粒径不得大于50mm。4.2试验区及试验参数4.2.1试验区桩试验区域拟定在渠道Ⅳ28+040~Ⅳ28+100段,详见附图1。4.2.2试验参数培养学生的阅读习惯,通过阅读欣赏短文,引导学生感悟大自然的美,激发热爱家乡的感情。语文生活,让学生认识到生活中处处有
