作者介绍了他们自己的实验研究，其中包括对位于波兰克拉科夫污水处理厂的公称单位容量为8,300 m~3的钢筋混凝土圆柱形水池的研究。墙体整体连接到基础环上，分两个阶段进行混凝土浇筑：每隔一段。这种水箱被归类为半无活性结构，由于其体积和几何形状，在硬化过程中有能力储存更多的释放热。在储罐安装阶段，由于裂缝，出现了大量罐壁渗漏情况。介绍了混凝土纵向变形和裂缝发展的测量，以及选定节段的裂缝宽度。此外，还讨论了三个选定节段之间竖向施工缝的应变和裂缝宽度扩展的测量。本文的研究为这种结构在施工过程中的实际行为提供了信息。
AbstractThe authors present their own experimental studies, which include research on a reinforced-concrete cylindrical tank with a nominal unit capacity of 8,300 m3, located in the sewage treatment plant in Krakow, Poland. The wall is monolithically connected to the foundation ring and was concreted in two stages: every second segment. This tank is classified among semimassive structures, which, owing to its volume and geometry, has an ability to store up a greater amount of released heat during the hardening process. At the stage of tank erection, because of cracks, numerous cases of leakage through the tank wall appeared. The measurement of longitudinal concrete deformation and crack development, together with the crack widths in selected segments, are presented. Moreover, the measurement of strains and crack-width propagation in vertical construction joints among three selected segments are discussed. The research presented provides information about the real behavior of such a structure under constr...
