电缆隧道圆形竖井结构设计方法研究
Study on Design Method of Circular Vertical Shaft Structure in Cable Tunnel
摘要
Abstract
As the design of circular vertical shaft is not explicitly defined in various industrial standards, the calculation methods of shaft's lateral pressure and circular horizontal radial load in domestic and foreign norms are analyzed and demonstrated based on the interpretation of relevant criteria, and three calculation methods are used to reach some reasonable conclusions. The results show that Rankine earth pressure formula is applicable to calculating lateral pressure of vertical shaft; reduction factor of 25% is introduced into horizontal radial load; 3 the load-structure method adopts active load and passive load pattern. The design method is mainly based on 2D load-structure method assisted by 3D load-structure method and 3D continuum FEM during the process of structure design.关键词
