Advanced soil reinforcement technology for geo-structure with long service lifetime

点击翻译按钮获取中文摘要

For reinforced soil walls, the accuracy of the current design model was evaluated, and the basic concepts of a design method for the load resistance factors were framed. A lifecycle cost estimation method that took into account the risk of seismic disasters was established. Furthermore, a laboratory test was developed to evaluate the long-term performance of the polymeric reinforcing material, and the performance of the high-density polyethylene(HDPE) geogrid was investigated in detail. An information and communications technology(ICT)-based monitoring system was developed for lifecycle management with actual structural data. These research results will contribute toward the construction and management of geo-structures with long service lifetimes.
