丘陵多雨地区机场场道地基处理施工优化措施及其应用

Optimized Measures and Application of Airport Runway Subgrade Treatment Construction in Hilly Rainy Area

结合上饶三清山机场建设项目,在了解场区地质、水文及气候特点的基础上,分析丘陵多雨地区场道地基处理过程中碰到的难点。通过准确把握工程难点,提出了适用于丘陵多雨地区机场场道地基施工优化措施,并将之成功应用于实际。实践证明,按照该施工优化措施处理后的场道地基,在压实度、地基反应模量及沉降变形三个方面均得到显著加强。该施工优化措施对于提高场道地基工程质量、保证施工进度具有重要意义。

Combined with Shangrao Sanqingshan Airport Construction Project,the article analyzes the difficulties existing in the runway subgrade treatment process of hilly rainy area on the basis of understanding the filed geology and hydrology an climate features.Aiming at the engineering difficulties,the article puts forward the optimized measures suitable for the construction of airport runway subgrade in hilly rainy area,and makes it successfully applied in the practices.The practices prove three aspects of compactness,subgrade reaction modulus and settlement deformation are obviously strengthened according to the runway subgrade treated by the optimized measures.This optimized measures of construction has the important significance to improve the runway subgrade engineering quality and to guarantee the construction schedule.
