高寒地区桥梁灌注桩施工工艺研究

新疆地区地理位置特殊，自然环境极为恶劣，对公路桥梁基础施工提出了更高的要求。桩基础是桥梁工程最常见的形式，高寒地区桩基础施工需要进行严格的质量控制。鉴于此，对采用钻孔灌注桩基础的桥梁基础施工工艺进行阐述，重点分析冻土区施工要点及解决措施，可为桩基施工和设计提供理论依据。

Construction Technology of Bridge Bored Pile in Alpine Region

The geographical location of Xinjiang is special, and its natural environment is extremely bad, thus it puts forward higher requirements on the construction of foundation of highways and bridges. The pile foundation is the most common form in bridge engineering, its construction requires strict quality control in the alpine area. Given this, the construction technology of bridge foundation which uses the bored pile foundation is described, the construction points and solutions are analyzed, which can provide a theoretical basis for the design and construction of pile foundation.
