考虑水平作用的地下室RC挡墙的改进设计方法

On improved design methods for RC retaining walls of basement under horizontal effect

通过工程实例,建立了考虑水平作用的地下室RC挡墙的力学模型,改进了地下室RC挡墙的结构设计:以竖向作用下的反弯点为界,分别对竖向跨中截面和底部支座截面进行设计;采用增大底部截面和底部双向加密配筋的措施可更有效的满足挡墙的承载能力和正常使用的要求。

Combining with the engineering cases,the paper establishes the calculation model for the basement RC retaining walls,from the load,bening moment,reinforcement,crack width and so on,analyzes the design methods for the basement RC retaining walls under the horizontal effect,and points out the respective design for the vertical cross section and bottom support section bordered by anti-moment point under the horizontal effect,realize the safety and money-saving of the retaining walls.
