Retaining structures: displacement and design
سال چاپ: ۱۹۹۲
چکیده مقاله:
The quest for rational methods of designing retaining structures has been pursued for many decades. The existing British code of practice was first published in 1951 and a committee attempting to revise it has been sitting for about 20 years; the record of other European countries is little better. A major reason for the difficulty lies in the importance of soil-structure interaction to the behaviour of retaining walls, and in particular the significance of displacement in governing the acceptability of a particular design.
The Eurocodes, which are currently under development will adopt a partial factor method for establishing safety and, incidentally, serviceability. At the same time, an editing group working on the British code has concentrated attention on serviceability, but its recommendations for calculations are rather similar to those of the Eurocode. The approaches proposed by both these groups will lead to some differences in the designs adopted for construction, when compared with conventional British design. The background to these approaches is discussed in this Paper.
