高速公路软基施工处理方法研究

高速公路软基施工处理方法研究摘要近年来随着高速公路的大量基本建设，工程施工中遇到的软基处理难题更加明显，已经成为危害工程施工质量、建设工期和工程预算的重要因素之一。在高速公路软基处理的关键技术研究中，存在很多决策制定。为了能科学研究高速公路软土工程施工解决方法，文中在搜集总结和反思世界各国参考文献的前提下，对高速公路软基处理和固定方法进行了全面剖析，并且对高速公路在各个软土条件下的设计与施工进行了全面讨论。仅有根据具体砂土采用有针对性的举措，融合全部可以用网络资源，有针对性地做好规划，采用切实有效可行的处理方法方法，才可以实现高效、高品质。最终阐述了软土地基形成的原因及路基厚度所在的位置，常用方法：表面解决法、置换法、承载力法、纵向排水法。关键词：高速公路；软基工程特性：软基处理TUDY ON CONSTRUCTION TREATMENT METHOD OFSOFT FOUNDATION OF EXPRESSWAYAbstractIn recent years,with the large amount of highway construction,the problem of softfoundation treatment in the construction is more obvious,which has become one of theimportant factors that harm the construction quality,construction period and project budget.In the research of the key technology of soft foundation treatment of expressway,there aremany decision making.In order to study the solution of highway soft soil engineering construction scientifically,on the premise of collecting,summarizing and reflecting on the references of variouscountries in the world,the paper makes a comprehensive analysis of the treatment and fixingmethods of highway soft foundation,and discusses the design and construction of highwayunder various soft soil conditions.Only by adopting targeted measures according to specificsand,integrating all available network resources,making targeted planning,and adoptingeffective and feasible treatment methods can we achieve high efficiency and high quality.Finally,the reasons for the formation of soft soil foundation and the location of subgradethickness are described.Common methods:surface solution method,displacement method,bearing capacity method,longitudinal drainage method.Keywords:A highway;Soft foundation engineering characteristics;Soft base treatment目录1绪论2软土工程特性的研究.32.1软土的定义..32.2软土的性质32.3软土勘察技术和手段研究现状52.4公路软基处理方法…52.4.1软基处理技术的发展.….62.4.2软基加固方案决策及优选方法.63高速公路软基的处理方法.….83.1高速公路软基存在的问题….83.1.1土体及处理软土路基的一般原则.83.1.2土体的物理参数.93.1.3处理方式的分类93.2针对软土路基所采取的具体施工方法.93.2.1表层处理法.93.2.2置换法.103.2.3加载法113.2.4竖向排水法113.2.5其他几种方法124结论…14参考文献..15致谢….17
