| The concrete cap, which was established on the top of the micropile, usually considered as an important structural component in micropile supported foundation systems. However, relatively few studies have been made on the load sharing behavior of the capped micropile foundation systems. The primary objective of this study is to assess the load sharing behavior of the capped micropile foundation systems. Therefore, a full-scale test on an instrumented capped micropile is conducted for establishing the load-displacement responses. Nonlinear numerical method was used to quantify the load sharing behavior of the pile cap and micropile respectively. As a result, it was found that the pile cap shares about 50% load from final loading steps in the case of 2 by 1 micropile foundation systems. In the case of 2 by 2, the pile cap shares about 30% load from final loading steps. In addition, the load sharing behavior of the micropile cap becomes larger with an increase in spacing and the battered angle of micropile respectively. |
