| Abstract: | Prestressed Concrete without bond is made up in the following procedure: before concreting, put the preprocessed stranded wire without bond into the form just like ordinary stranded wire, then place the concrete. When the concrete has reached the design strength, stretching can be carried out. This paper presents the construction technology and technical keys of circumferretial prestress without bond for Zhangyang U-shape thin-shell flume. |
