Other Abstract 压力管道混凝土开裂后内力变化、裂缝发展、管道危险度,是温度应力的研究课题,又是确定该类管道裂缝处理方案的前提,目前,这一问题国内外可供参阅的资料很少。本文根据实测温度资料和对裂缝发展过程的观察记录,从结构力学和钢筋混凝土结构的基本原理出发,推导了内力计算公式,制定了计算表格。这是一种较为简便地解决压力管道混凝土开裂后,内力如何变化问题的途径,有助于分析裂缝如何发展,管道危险度如何估计等问题。这一研究成果已及时地用于某倒虹工程裂缝处理方案的论证分析,使管道裂缝原因分析和处理方案得到较好的解决。 
;  How to calculate the temperature stresses of the pressure pipe after the concrete rending is of importance to understand expansion of crevice and estimate danger degree. According to the actual measured temperature data and the data on the expanding processes of crevices, the authors deduced the calculation formulas and drew up the calculation lists on ground of the basic principles of structural mechanics and reinforced concrete structure. This is a simple and easy way to size up internal-force changes while the pressure pipe concrete rended. The calculation method has been used to the analysis of crevice settlement in an inverted siphon.
