| 摘 要： | 安康防洪大堤修建运用已经18年,因江北河堤的建成以及其它各种人类活动的影响,原城堤是否还满足百年一遇设计洪水.经论证,江北河堤的修建,减小了河道过水断面面积5%,致使同级流量下的相应水位抬高0.1～0.22m,但对256.8m的堤顶高程来讲,仍能保证30500m3/s流量的泄洪能力.其它人类活动对河道有一定影响,须加强观测,进行分析、论证以便采取相应措施,确保大堤安全.

| Abstract: | Ankang Flood Bank has been in use for 18 years.Because the Northern Bank has been completed and because of other kinds of human activities,it is doubted whether Ankang Flood Bank can satisfy and design flood that is not likely to happen in a century.After argumentation,the construction of the Northern Bank reduces the water flow section by 5%,and raises the water level about 0.1- 0.22 meter.As the Bank is 256.8 meters high,the flood discharge at 20500m~3/s is still guaranteed.And other human activities have certain effects on the river way.We should enhance our investigation,analyze and demonstrate the effects so that we can take corresponding measures to secure Ankang Flood Bank. |
