1、半填半挖路基施工作业指导书1、目的指导半填半挖路基工程的实施。2、适用条件及范围本作业指导书适用于半填半挖路基工程的实施。3、编制依据3.1公路路基施工技术规范；3.2公路工程质量检验评定标准；3.3安邵高速公路两阶段施工设计图第二册路基、路面设计图；3.4湖南省高速公路精细化施工实施细则；3.5有关现场踏勘调查资料，水文地质调查资料。4. 施工工艺4.1. 工艺流程施工准备测量放线地表清理 挖台阶路堑开挖基床底层以下填筑、埋设土工格栅 基床底层填筑、埋设土工格栅 基床表层填筑 4.2. 施工方法及要求半填半挖路基轨道下横跨挖方与填方两部分时，挖方区分硬质岩及土质、软质岩、强风化硬质岩分别采用
2、爆破开挖或机械开挖施工。挖方区按设计坡度施工完成后，全断面同时填筑施工。填筑施工按设计要求采用合格填料，分层填筑，机械压实。当挖方区为硬质路堑时，如为节理不发育的非可溶岩时，基床表层换填10cm厚的C25混凝土，如为可溶岩及节理发育的硬质岩时，基床表层应换填0.4m的C25混凝土，同时应采用C15片石混凝土或混凝土嵌补凹坑、溶沟、溶槽及溶蚀裂缝等。基床以下路堤与路堑连接处开挖台阶，台阶高不小于1m。挖方为土质、软质岩及全风化硬质岩时，挖至设计标高后，分层换填符合200km/h以上规范及设计要求的填料。基床以下路堤与路堑连接处开挖台阶，台阶高不小于0.6m。对边坡设计有边坡加固的，采用土工格栅对
3、边坡进行加固。4.3. 过渡段路基工程施工质量保证措施（1）施工中把路基工程作为主体结构工程来对待，保证路基工程质量零缺陷，满足基础高平顺性要求。（2）施工前组织参加施工的管理人员、技术人员、作业人员进行技术培训和交底，使全体施工人员了解设计意图，熟悉工程内容、特点、施工方案及各项要求，确保工程顺利进行。编制路基重点（控制工程）施工组织设计以及路基各类工程施工作业指导书用于指导施工。（3）在进行地基处理前，根据施工图设计提供的地质资料进行现场复核和补充地质勘探，并结合室内土工试验进行地基条件评价，确定地基处理措施。（4）路基填筑施工前对设计取土场及利用的填料进行核对、确认，并在施工中对进场填料
4、进行复查和试验，确保填料种类、质量符合设计要求。填料拌和、加工实行工厂化生产。（5）填筑施工时选取有代表性的填料进行摊铺压实工艺试验，试验填料碾压含水量、摊铺厚度、碾压机械、碾压遍数等施工工艺参数，经检验地基系数K30、压实系数K（改良细粒土）、动态变形模量Evd（级配碎石）、孔隙率n均满足设计要求后，确定施工工艺参数，再进行大面积路基填筑。路基填筑施工严格按工艺试验确定的参数施工，严格过程监控和质量检验、记录。（6）路基作为变形控制十分严格的土工构筑物，施工中根据设计要求对沉降变形进行动态监测，构筑纵横立体监测网络，对路基本体及地基沉降进行全面、系统的监测，并通过沉降预测、评估技术，达到优化
5、设计、控制工后沉降，确定无碴轨道结构施工和铺轨时间。（7）过渡段严格采用设计的填料类型与路基同步施工，保证刚度均匀过渡，使不均匀沉降满足设计及规范要求。（8）接触网支柱基础及声屏障基础在路基填筑至相应标高且沉降稳定后，采用螺旋钻机干式成孔，出碴直接装入自卸车远弃，旋挖钻机选用轮胎式或橡胶履带式，以此减少钻机对基床表面的磨损破坏。综合接地线、观测元器件、各类预埋管道与路基填筑同步施工，一次预埋合格，避免返工开挖，破坏路基稳定。运架梁车需通过的路基地段提前安排施工，保证在运架梁作业前1个月完成该段路基施工。（英文版 ） Two regulations promulgated for impleme
