Resilient and Sustainability Analysis of Flexible Supporting Structure of Expansive Soil Slope

In order to improve the ability of flexible support structure resist, recover and adapt failure expansive soil slope, it is necessary analyze study its structural resilience systematically. Based on long-term field monitoring test slope with along south line Guinan key project, combined whole life cycle assessment (LCA), this paper discusses theory method resilient design a structure. The results show that variation trend geogrid strain basically consistent pressure at side slope. It increases gradually increase in rainfall rainy season. When decreases significantly dry season, will shrink accordingly realize periodic regulation lateral deformation soil. analysis shows carbon emission 10% rigid structure, resource energy consumption about 50% lower than
