| 摘要： | Geosynthetic reinforced soil (GRS) piers offer a low-cost, quick-construction alternative to the elaborate, high-priced reinforced concrete bridge piers that suppport most of the world's bridges. Consisting of alternating layers of compacted soil separated by geosynthetic sheets, the GRS piers offer ease of construction, durability, and strength. This article describes a GRS pier at the Turner-Fairbank Highway Research Center in McLean, Virginia, that was loaded to 9800 kilonewtons and 930 kilopascals (2.2 million pounds force and 135 pounds force per square inch, respectively), which is well beyond any intended service load. The technology itself is thousands of years old; however, engineers of today are dismissive of such overtly simple technologies. |
