空箱式挡土墙结构设计研究

Study on the Structure Design of Chamber Retaining Wall

为了解决结构布置空间不足时的水流分隔问题,研究了空箱式挡土墙的结构设计,以某电厂取水和排水明渠之间隔水的空箱式挡土墙为例,运用STAAD.PRO软件建立三维模型,确定基本工况与荷载组合后进行分析计算;结合传统构件分析方法,进行地基承载力、沉降、稳定、裂缝验算,并进行构件强度设计。结果表明,两种方法结合,可更真实的模拟结构工作状态,设计结果可靠、合理。

In order to solve the problem of water separation when the structure layout space is insufficient,study on the structure design procedure of chamber retaining wall.Take a retaining wall in a certain power plant as an example,using STAAD.PRO software to establish 3D modeling,determine the basic condition and load combination and then analysis;Combined with the traditional component analysis method,carried on bearing capacity checking,settlement checking,stability checking,crack checking and component strength design.The results showed that the two methods can simulate the working state of the structure more realistically,and the design results are reliable and reasonable.
