随着经济的快速发展,桥梁成为连接经济发展的重要枢纽,桥梁工程也进入了快速建设时期。地基作为桥梁工程的基础,在桥梁工程施工中具有非常重要的意义。结合多年桥梁工程的地基施工经验表明,由于地基的冻融作用和不良冻土地区的影响,会对基础施工造成较大的影响,给工程的质量带来较多不利的因素,影响工程竣工后的正常使用。所以在冻土区进行桩基础施工时需要结合大气温度、水文地质条件等多方面的影响因素进行分析,从而保证冻土区桩基础的稳定性。现分析了桥梁工程施工中冻土地基的特性,并进一步对冻土地区桥梁桩基础施工技术进行了阐述。
With the rapid economic development, the bridge has become an important hub connecting economic development and the bridge engineering has entered a period of rapid construction. As the foundation of bridge engineering, foundation is of great significance in bridge construction. The experience of foundation construction combined with many years of bridge engineering shows that due to the freezing and thawing of the foundation and the influence of the poor permafrost region, it will have a greater impact on the foundation construction and bring more unfavorable factors to the quality of the project, which will affect the completion of the project The normal use. Therefore, in the construction of pile foundation in the permafrost region, it is necessary to analyze the influencing factors in combination with the atmospheric temperature and hydrogeological conditions so as to ensure the stability of pile foundation in permafrost regions. The characteristics of frozen soil foundation in bridge construction are analyzed, and the construction technology of bridge pile foundation in permafrost regions is further elaborated.
