摘要

某冷却塔已使用20多年

存在一定程度的老化和破损

对其外观缺陷、混凝土碳化程度、钢筋锈蚀程度及倾斜度等进行检测鉴定

应用有限元方法

计算该冷却塔在风荷载、温度作用、重力荷载单独作用和组合作用下的内力和变形

并取组合作用进行整体稳定性和局部稳定性分析

验算塔身裂缝发展情况。结果表明

冷却塔刚度、承载力、安全系数、整体稳定性和局部稳定性均能满足现行规范的规定

塔身裂缝除局部筒壁不满足最大裂缝宽度限制的要求外

其它范围均满足。根据检测鉴定及有限元计算结果

对冷却塔采用粘碳纤维布、混凝土表面防碳化处理、钢筋除锈防锈等加固补强措施。

Abstract

A cooling tower has been used for more than 20 years

and there is a certain degree of aging and damage.The appearance of the tower

the degree of carbonation of concrete

the degree of corrosion of steel bar

and the degree of inclination are detected.Using finite element method

the internal force and deformation of the cooling tower are calculated

when the wind load

temperature load and gravity load work respectively and simultaneously.The overall stability and local stability analysis

the crack development under the combined loads are carried out.The results show that the rigidity

strength

safety coefficient

overall stability and local stability coefficient of the cooling tower can meet the requirements of the specification.In addition to some area of the tower

the crack width of the other of the body is satisfied with the maximum crack width.According to the results of the test and finite element calculation

the strengthening measures of the cooling tower are as follows:sticking carbon fiber cloth

anti-carbonation treatment of concrete surface

derusting and antirust measures

etc.
