路堤土石方填筑、基床表层施工前，先进行试验段的施工，根据所采用的摊铺压实机械，进行填筑工艺试验，确定填料级配、含水量、摊铺厚度、压路机行走速率和碾压遍数等关键的施工工艺参数，编制路堤填筑试验段成果报告报与监理单位审核通过后作为路基填筑施工的重要指导依据，并严格按此报告指导以后路基填筑施工。路桥以及路堤与横向结构物、涵洞等过渡段与路基同步施工，大型机械不能到达或不便碾压的缺口处采用小型压实机械压实。为了保证过渡段填筑质量，过渡段与相邻路堤按水平分层一体同时填筑，但确有困难不能同时施工的，为保证路基施工进度，可采取在桥台后预留一定长度的路堤填筑段并做出台阶，待后期过渡段施工条件成熟后与过渡段一起施工。路基与桥台、路基与涵洞、路基与横向结构物等过渡段填筑压实质量和沉降控制是路基工程的重点。施工前，根据线路不同地质情况，选用 N10轻型动力触探、N63.5 重型动力触探、标准贯入、静力触探四种原位测试方法的一种结合室内土工试验进行补充勘察，有疑问时进行地质补钻，与设计所采用地质进行核对。岩溶发育区采用电法物探辅以验证性钻孔查清基底岩溶情况。确保不因地质勘察原因造成路基沉降控制问题。路基防护紧跟路基填筑尽早展开施工。早日起到防护作用。防护工程不能紧跟时，采取临时防排水措施进行临时防护。所有路基圬工采用人力施工，所有砌筑砂浆采用机械按技术规范所要求的数据拌合,而混凝土采用该标段的混凝土搅拌站材料。其他绿色防护安排在适宜季节。5.2 施工方法5.2.1 路基开挖施工5.2.1.1土质路堑开挖施工1、施工原则：开挖路堑前作好截水沟，并视土质情况作好防渗工作，土方施工期间修建临时排水设施。临时排水设施与永久性排水设施相结合，流水不得排入农田、耕地，污染自然水源，不得引起淤积和冲刷。2、测量放线：按照设计图给定的测量数据，用拓普康332N 型全站仪测放出开挖边线，并用石灰醒目标示出边线位置，以利于施工过程中辨识提高工作效文档编码:CH8K2R2X2B8 HY5F6I9B4K7 ZK8F10Z8C5W3文档编码:CH8K2R2X2B8 HY5F6I9B4K7 ZK8F10Z8C5W3文档编码:CH8K2R2X2B8 HY5F6I9B4K7 ZK8F10Z8C5W3文档编码:CH8K2R2X2B8 HY5F6I9B4K7

率。3、清表：清除的耕种土作为挖方碎落台、边坡绿化所需种植土。4、开挖：根据现场不同情况，采取横挖法方式进行开挖，作为路基填料的土方，分类开挖及使用，非适用性材料按弃方置于弃土场。土方开挖自上而下顺序逐级开挖，挖方边坡高度小于10米的一坡到顶，在边坡高度大于 10 米采用阶梯形边坡，第一级台阶高8m，以上每隔 10 米高边坡平台，边坡平台宽1m2m。边坡采取开挖一级防护一级的方式进行，待上级边坡锚固工程全部实施并产生加固作用后方可进行下级边坡的开挖作业，以确保坡体稳定和结构安全。开挖至边坡线前，应预留一定宽度，预留宽度应保证刷坡过程中设计边坡线外的土层不受到扰动，边坡上稳定的孤石应保留，开挖至路床部分后，如不能及时施工宜在路床顶标高以上预留300mm 厚的保护层。路床土含水量高时应采取透水性能较好的材料进行换填。5.2.1.2石质路堑开挖施工根据岩石的类别、风化程度、岩层产状、岩体断裂构造施工环境等因素综合考虑确定最佳开挖方案。对于软石和强风化岩石能用机械开挖的采用机械开挖，不能用机械直接开挖的石方，采用爆破法开挖。石方开挖中，先利用推土机从上而下清除覆盖层土，采用松动爆破、小爆破和光面爆破方法施工。逐级开挖，逐级按设计要求进行防护。5.2.2
