| 摘 要： | 体外预应力是预应力钢绞线布置在混凝土截面之外的预应力,它是预应力体系的重要分支。本文采用有限元软件对体外预应力圆形水池的池壁进行受力分析,通过比较施加预压力前后池壁内力的变化,以及对比常规结构(体内预应力)圆形水池池壁内力,肯定了体外预应力在圆形水池中抵抗池壁环拉力和控制抗裂度方面的作用,并展望了体外预应力的应用前景。

Analysis of Restrained Effect on Circular Tank Wall with Horizontal Ring Plate |

| Abstract: | External prestress is prestressed steel strands which are arranged in the concrete section outside,it is an important branch of prestressed system.This paper analyzed the stress of the external prestressed circular tank wall by finite element software,by comparing the changes of internal force before and after applying pre pressure,as well as compared to conventional structure（internal prestressed） circular tank wall internal force,external prestressed resistance ring tension and crack controlling function in the circular tank wall were affirmed,and its application prospect was estimated. |
