초록

Excavation support systems are the temporary earth retaining structures that can prevent the lateral movement of soils. The systems are initially performed before other construction operations and have a great impact on the entire construction period. The temporary support system in Korea have been carried out generally along with installing supports, which are struts, tiebacks, and rakers. However, most of existing support systems in application relatively have limitations such as cost increase, construction configuration, and displacement occurred with support systems. Thus, a new retaining support system (referred to as the SSR, New Construction Technology No. 533) was developed to solve the aforementioned problems. This study introduces the design, construction, and maintenance of the SSR system under the different construction conditions. The behavior and characteristics of the SSR system were identified based on the case studies.
