Construction Technology and Hidden Danger Prevention Measures for Pile Foundation of High-speed Bridges in Mountainous Areas

摘要:

针对山区高速公路桥梁桩基施工中地质条件复杂、隐患类型多、质量管控难度大的现实难题,文章对山区高速桥梁桩基施工工艺及隐患防控措施展开系统性研究,通过梳理山区桩基施工的环境特征与工艺选型原则,对比分析不同成孔工艺的适用场景与技术特性,深入剖析成孔、成桩及特殊地质段的常见隐患成因,从工艺参数优化、分级隐患防控、特殊地质处置、全流程管控4个维度提出针对性的防控措施,以期为同类山区桥梁桩基施工的质量管控提供工程实践参考。

Abstract:

In response to the practical difficulties of complex geological conditions, multiple types of hidden dangers, and difficult quality control in the construction of bridge pile foundations on mountainous highways, this article conducts a systematic study on the construction technology and hidden danger prevention and control measures of bridge pile foundations in mountainous areas. By sorting out the environmental characteristics and process selection principles of pile foundation construction in mountainous areas, comparing and analyzing the applicable scenarios and technical characteristics of different drilling processes, this article deeply analyzes the common hidden danger causes of drilling, piling, and special geological sections. Targeted prevention and control measures are proposed from four dimensions: process parameter optimization, graded hidden danger prevention and control, special geological disposal, and full process control, in order to provide engineering practice reference for quality control of bridge pile foundation construction in similar mountainous areas.
