| 摘 要： | 日照引起的混凝土空心高墩温度应力较大,不能被忽视。在考虑温度应力时,需要考虑混凝土空心高墩的结构特点,以获得温度应力的作用特点。以某铁路桥梁空心高墩为例,分析了墩身的结构特点、温度应力分布特点以及温度应力对墩身的不利影响,并对预防措施进行了必要说明。

| Abstract: | The thermal stress of concrete hollow high pier induced by sunlight is comparatively high,which can′t be ignored.When considering the thermal stress,the structural characteristics of concrete hollow high pier need considering in order to get the role characteristics of hollow concrete high pier.Taking the hollow high piers of a railway bridge as example,the paper analyzes the structural characteristics of piers,the distribution characteristics of thermal stress and the adverse effect of thermal stress on piers,as well as puts forward necessary instructions on the preventive measures. |
