英文摘要
Micropiles are used in various applications, including small capacity micropiles used for underpinning and seismic retrofitting of existing foundations, and high capacity foundations for new structures. Hollow bar micropiles have an added advantage as they provide fast installation with a high degree of ground improvement. The current practice for construction of hollow bar micropiles is limited to drilling bit/hollow bar diameter ratio of 2.5 or less, which limits the diameter of the micropile and hence its capacity. Additionally, micropiles are used in groups to support structural loads. Considerable research efforts, experimental and numerical, have evaluated the influence of pile spacing on group behavior and efficiency, yet the outcome
