1、1 路基土石方施工技术交底施工准备 施工测量在开工前先进行施工测量，包括导线、中线及高程的复测，水准点的复查与增设，测量与绘制横断面。施工测量的精度符合公路勘测规程（JTJ061-99）的要求。并将测量方法及成果资料签字后交送监理工程师。经监理工程师批准后方可施工。在开工之前在现场放出路基坡脚、路堑堑顶、截水沟、边沟、护坡道、取土坑、弃土场等的具体位置，标明其轮廓，提请监理工程师检查批准。调查与试验路基施工前对施工范围内的地质、水文、障碍物、及各种管线等情况进行详细调查。对图纸所示的利用挖方、借土场的路堤填料取有代表性的土样进行试验，试验方法按公路土工试验规程（JTJ051-93）执行，试验项

2、目按“技术规范”要求进行。防水、排水施工前做好路基的各种防、排水设施，挖设排水沟，并保持其处于良好的排水状态。清理场地路基工程施工前，清除施工范围内的树木、灌木、原地面以下100-300mm2 内的草皮、农作物的根系和表土。且堆放在弃土场内或经监理工程师认可地点。场地清理完成后，全面进行填前碾压，使其密实度达到规定的要求。雨季施工雨季施工前，根据现场具体情况确定可进行雨季施工地段，严格按照 公路路基施工技术规范（JTJO33-95）中雨季施工的有关规定执行，并编制实施性的雨季施工组织计划，提交监理工程师审查批准。雨季填筑路堤时，随挖、随运、随填、随压。每层填土表面筑2-3%的横坡，并在雨前和收

3、工前将铺填的松土碾压密实。路基挖方施工对于较长的路堑采用纵挖法施工，短而深的路堑采用横挖法施工。路堑开挖以机械施工为主，靠近基床底层表面及边坡部分辅以人工开挖。石方开挖采用小型或松动爆破，岩石边坡采用光面爆破施工。土石方调运近距离采用推土机推运,远距离采用挖掘机、装载机配合自卸汽车运输。1）土方开挖 路堑土方开挖施工工艺路堑开挖施工工艺流程见附表5 的深挖路堑段施工工艺框图。施工控制 路堑边坡根据测设的边桩位置，当机械开挖至靠近边坡0.3m 时，改为人工修坡。文档编码:CG6B7W5H8A7 HT3Z2Y6M10Z8 ZR7O2V9B5H8文档编码:CG6B7W5H8A7 HT3Z2Y6M10
