摘要
结合工程实例,简述了在民航机场领域孔内深层强夯桩法处理地基的设计,介绍了孔内深层强夯法桩的施工与检测,并简要进行了经济分析,工程实践证明,该孔内深层强夯法桩处理地基具有强力的挤密、置换作用,桩体同时具备竖向排水通道,有利于地基土排水固结。处理单位面积的价格比碎石桩便宜,该方法处理深度深、综合效果好、施工工艺相对简单、对周围坏境影响相对较小,可为类似工程提供施工经验。
Combining with engineering examples,the paper illustrates the foundation processing design with in-depth dynamic compaction pile method in civil aviation airport,introduces the construction and detection of in-depth dynamic compaction pile method,and carries out simple economic analysis. The engineering practice proves the advantages of the above-mentioned method,such as strong compaction and replacing role,vertical drainage channel of the pile which is good for foundation drainage consolidation,the price of processing unit-area is lower than that of the gravel pile,deep processing depth,good comprehensive effect,simple construction technology,little impact upon surrounding environment,which can provide construction experience for similar engineering.
