摘要
介绍了常规深基坑开口型板式支护的类型及其特点,分析了开口型板式支护设计需考虑的关键因素,包括变形控制标准的考虑、支撑端部的支座设计和邻近结构体的稳定性分析等,并推荐了支座设计时较实用的计算公式。文中的工程设计实例进一步介绍了结合具体环境条件的开口型板式支护的设计方法,以及支护结构开口处的加强措施,并验证了开口型板式支护的有效性,对深基坑支护设计有一定的借鉴意义。
The types and characteristics of open-type embedded retaining walls in deep foundation pits are introduced.The key factors in design are analyzed,including the consideration of control standards of deformation,the sustainer design of horizontal bracing and the stability analysis of neighboring structures.Formulas for the sustainer design are recommended.Several examples show the design method under specific circumstances.Relevant measures on structural strengthening of the embedded retaining walls in open area are proposed.The validity of the open-type embedded retaining walls is proved,and it is helpful to other deep foundation pits.
