Structure design of a super-high retaining wall

Zhu Xiangdong(Shenzhen Branch of the Institute of Architecture Design and Research Chongqing University，Shenzhen 518052，China)Abstract:In order to handle the slide accident of a 22-meter-height retaining wall which was originally gravity style, the reinforced concrete buttress wall was designed. Some principles for design of super-high retaining walls were proposed. Measures, such as using decompression platform to decrease soil pressure, adding geo-textile as well as changing downward sloping water outlets to upward sloping ones etc., were introduced. The purpose of good reliability and less cost for the super-high retaining wall easily achieved.

Keywords:gravity retaining wall; reinforced concrete buttress retaining wall; decompression platform; geo-textile
