Title: The Bearing Characteristics and its Influencing Factors of Reinforced Soil Foundation
Abstract: The reinforced soil foundations have been widely used in various geotechnical engineering applications, such as bridge approach slab, bridge abutment and so on. However, many problems of reinforced foundation still need to be solved and the behavior of the reinforced foundation requires further study. Therefore, finite element analyses were conducted on unreinforced and reinforced clay subgrade soil to evaluate the influence of various factors affecting the performance of strip footing on studied soils. Conclusions are drawn: the effective reinforcement depth is about 1.5B for the reinforced soil and it is independent of the geogrid type; At a given settlement, the bearing capacity of the footing decreases with the increase in reinforcement spacing, with larger decrease rates at small spacings; A geogrid with a tensile modulus ranging from 5MPa to 25MPa will maximize the benefits of the reinforced soil footing, etc.
