| 摘 要： | 提出了适用于流量影响线法的换算雨量荷载系列,并在广东省综合单位线法基础上利用VB程序绘制出广东省相对于设计频率为1/100的换算雨量荷载等值线图.在勘测到桥梁墩台的历史水痕后,对该桥址处进行流量影响线标定,确定影响线各参数值.将换算的雨量荷载系列在所标定的流量影响线上加载,即可得出相应于该设计频率的最大洪峰流量.广东省... |

| Abstract: | The conversion rainfall load series flow influence line was proposed.VB program was used to draw out the conversion rainfall load series contour map of Guangdong Province relative to the frequency of 1 / 100.The investigation of heights of water traces in the history of bridge piers was involved.Demarcating the flow influence line of the pier is used to determine the parameters.The design peak flow of corresponding frequency can be calculated when the conversion rainfall load series was added on the flow in... |
| Keywords: | flow influence line the calculating period the rainfall load series |
