摘要
针对永咸高速公路沿线湿陷性黄土分布范围大、湿陷等级多的问题,从强夯处理设计方案、处理工艺、质量控制及施工安全操作等几个方面,介绍了桥涵地基及台背强夯处理技术。实践证明:采用桥涵地基及台背强夯处理技术对湿陷性黄土地区的高等级公路建设具有很强的可操作性,同时具有良好的经济及社会效益。
There are lots of loess area and more settlement by soaking along Yongxian Expressway. The strong pounding treatment of bridge and culvert foundation and abutment is introduced from design scheme, technology, quality control and safety. The practice proves that the treatment is feasible in loess high grade highway construction, and has better economic and social benefit.
