摘要

金属波纹结构的更新技术可以通过封装方法对现有钢筋混凝土结构进行高效经济的改造。然而，这种结构可能会受到不利的温度影响，再加上交通荷载，可能会影响结构的运行可靠性。本文讨论了三层圆柱结构应力-应变状态的评估方法。该技术基于热弹性理论。研究分两个步骤进行:确定结构的温度场，然后计算温度应力和变形。计算结果表明，最高和最低环境温度对三层结构温度场和应力的影响达到了显著水平。

Study of the temperature field and the thermo-elastic state of the multilayer soil-steel structure

The technology of renewal of metal corrugated structures allows efficient and economical reconstruction of existing reinforced concrete structures by the method of encapsulation. However, such structures can be exposed to adverse temperature effects that in combination with traffic loadings could influence the operational reliability of the structures. This article deals with the method of evaluation of the stress-strain state of a three-layer cylindrical structure. The technique is based on the thermo-elasticity theory. The study is performed in two steps: determining the temperature field of a structure, and then calculating the temperature stresses and deformations. As a result of calculations, it was established that the level of temperature field and stresses in a three-layer structure caused by the maximum and minimum ambient temperatures can reach a significant level.
