Application and Analysis of the Reinforced Retaining Wall with Geo-grid

With the development of economy and expansion of cities in China, land resource for construction is becoming scarce. Some important infrastructures, such as airports are located in mountainous areas where the engineering geological conditions are complicated. Due to the limitations of natural conditions like steep terrain and deep-cutting gorges, the high embankment engineering has no natural sloping conditions. So the stability of high embankment engineering possesses a critical problem at present. Since the specific structure of the geo-grid can embed and occlude the soil particles, structure of reinforced retaining wall with geo-grid is widely used in high embankment engineering. However, there are very few theoretical explanations of such design. Here, we present a theoretical calculation of reinforced retaining wall with geo-grid based on strength reduction finite element method. This paper also proves the adaptability of reinforced retaining wall with geo-grid in the engineering under complicated geological conditions and the reliability of the established calculation method in the design and calculation of reinforced retaining wall with geo-grid.
