지반네일보강토체 전면부에서 노출된 지반네일의 연직 방향 연결에 의한 보강효과

The soil nailing method have been developed on the basis of experimental works as well as theoretical backgrounds. As (or the experimental research works, most of the data have been measured during the application of load in service. However, not only the soil-nailed structure behavior in service but also the failure behavior of the structure are the major concerns to evaluate and even establish a design method of soil-nailed walls. In this paper (or the apprehension of behavior in the soil-nailed structure which the front of nail is connected, a relatively large-scale experiment was carried out to Figure out the failure behavior of soil-nailed wall. A number of data have been acquired and analysis.
