通常情况之下,我们认为软土的成因是由于第四纪后期地表水所形成的沉淀物质经过一系列自然作用下而形成的地质较软的地基结构。对于软土地基,其不仅具有承载能力弱以及含水量大的特征,其还有压缩性较强的特点,因此,在进行公路工程施工项目中,处理好软土地基属于一项十分艰巨的任务,对整个工程项目的质量产生着极其重要的影响。如是不能及时地处理好软土地基,将会造成施工段路面沉陷以及桥头跳车等风险,对工程项目完工后的使用功能产生一定影响。所以,掌握科学有效的软土地基处理方法,对保证公路工程的施工质量方面十分重要。为此,作者根据多年的实践经验,客观分析了公路工程项目中软土路基的设计与处理中出现的问题,并就如何处理好这些问题提出了建议措施。
Under normal circumstances, we believe that the cause of soft soil is due to the late Quaternary sediment formed by surface water after a series of natural formation of the soft geologic foundation structure. For soft ground, which not only has the characteristics of low carrying capacity and high water content, but also has the characteristics of strong compressibility. Therefore, it is a very arduous task to deal with soft ground in the highway construction project , The quality of the entire project has an extremely important impact. If the soft soil foundation can not be handled in a timely manner, it will cause the risk of road surface subsidence at the construction section and bridge jumping. This will have an impact on the use of the completed project. Therefore, to master the scientific and effective method of soft soil foundation treatment is very important to ensure the construction quality of highway engineering. Therefore, based on many years of practical experience, the author objectively analyzes the problems in the design and processing of soft soil roadbed in highway engineering projects and puts forward some suggestions on how to deal with these problems.
