| Abstract: |
| The standard diagram and size of the general buttress are given in the standard atlas of buried pressure water supply pipe. However, there are some imperfections in the standard atlas of horizontal piers when used. When the design parameters are beyond the standard atlas, the size of the buttress can"t be found. When the actual parameters are not equal to the parameters in the figure, only the approximate value of the butt size can be obtained from the figure and the error is larger. Extended base rigid angle of the buttress is greater than the 45 degree rigid angle of concrete in the standard atlas. This leads to the structure of the buttress unsafe. No checking calculation of anti-overturning stability and base stress of buttress. In view of this, the type and size of the horizontal buttress in the standard atlas have been revised. The checking calculations is revised and improved and also given an example. |
