吉林大学交通学院自学考试 毕业论文（设计）任务及要求 题目名称 路基施工及湿软路基的处理 学院名称 吉林大学交通学院 专业名称 道路与桥梁工程 学生姓名 起止日期 2010年5月----2010年8月 指导教师 论文摘要 路基作为重要组成部分，它既是路线的主体，又是路面的基础。路基施工是公路工程施工的重要环节之一，路基填筑质量及其稳定性决定着公路质量的好坏及其使用寿命的长短。路基质量的好坏，关系到整个公路的质量及汽车的正常行驶。而湿软地基又是路基施工过程中经常碰到的施工难题，湿软地基处理的好坏又直接关系到路基的质量。因此，我们要高度重视路基施工，做好施工工作。在工程所在地要具体调查了解公路沿线及土源等作业范围内的土质的液限、塑限、塑性指数及含水量情况,制作标准击实试验和土的强度试验,制定施工方法。根据水文地质情况,进行分类、整理,结合以往的施工经验制定出路基各种不同类型土质、含水量的切实有效的施工方法及路基基底处理方案,防止在施工中出现盲目性,避免走弯路,以保证工程质量和进度。 关键词：场地清理；路堤填筑；路基压实；湿软地基处理 Abstract Foundation as an important component of both is the main route, is the basis of the road. Roadbed construction is an important part of highway construction is one of quality and stability of the roadbed filling the road quality is good or bad decision and the length of life. Subgrade quality is good or bad, the quality of the entire road and the cars normal driving. The soft ground is frequently encountered during the construction roadbed construction problems, soft ground treatment of the good or bad is directly related to the quality of the roadbed. Therefore, we must attach great importance to embankment construction, doing construction work. Located in the project to specific investigation along the road and soil source within the scope of operation of liquid limit and plastic limit, plasticity index and moisture, make standard of soil compaction test and construction method, strength test. According to the hydrogeological conditions, classification, sorting, combining the construction experience of the past for the subgrade soil water content, different types of effective construction methods and treatment of subgrade base solution, prevent blindness in construction, avoid detours, appear to ensure the engineering quality and
