摘要

This paper presents a case history of design and construction of a geotextile reinforced soil-metal (GRS) 2040 mm diameter structural plate culvert under a 42 m high embankment at a mine in South America. The geotechnical data indicated that the underlying SAPROLITE and laterite soils were very soft with predicted consolidation settlement under the conduit and embankment of up to 3m. Due to the complexity of the problem, two-dimensional non-linear finite element analysis was employed to analyze the soil-structure and soil-geotextile interaction. Results showed that the composite system considerably improved the performance of the culvert under the considered loading conditions. The structure was constructed in 2015 to 2016 and it is reported that the structure is performing satisfactory. The composite GRS-culvert system provided a viable solution for challenging site conditions.
