摘要
通过对某挡土墙滑坡事故的处理,重新设计了22m超高扶壁式钢筋混凝土挡土墙,提出了超高挡土墙的设计原则,详细介绍了设置减压平台降低土压力、增加土工布、改向下倾斜的泄水孔为向上倾斜等构造措施。证明通过正确的概念设计和构造加强措施,超高挡土墙的设计可以做到安全可靠、经济合理。
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.
