Changes in retaining wall design

摘要

In this code comparison research every revised code included in this comparison yielded savings in terms of economy. EC 2-1 is approximately 5% more economical than BS 8110 (1997). The water retaining codes generally give an average increase of approxi- mately 7.2% on cost when compared with then respective non-water retaining partnering code (excluding CP 2007 which was very uneconomical). There is also a definite convergence in water retaining and non-water retaining code design philosophies.
