摘要

本文介绍了下水道地下建筑钢结构退化的实验研究结果。结果显示了有害气体元素（硫、氢、氧）在下水道管道壁厚上的分布，以及金属显微硬度随氢含量和使用寿命而变化的特征。为了证实金属随着氢浓度的增加而软化，测量了晶格的应力（畸变应力）。

Corrosion Degradation of Long-Term Operated Steel Sewer Pipes

The results of the experimental study of the degradation of steel structures of sewer underground constructions are presented. The distribution of harmful gas elements (sulfur, hydrogen, oxygen) over the wall thickness of sewer pipes along corrosion defects in the form of pits, as well as the character of changes in the microhardness of the metal depending on the hydrogen content and service life, are shown. To confirm the metal softening with increasing hydrogen concentration, the stresses of the crystal lattice (distortion stresses) were measured.
