| 摘 要： | 赣江下游河道近年来受河床采砂、航道整治等影响,河床下切、水位下降,河床形态发生变化,该段航道整治参数也发生变化.在对赣江樟树至外洲河段河床变化计算分析的基础上,结合河床下切对河道水文特性影响的分析,依据最低通航水位及航道整治线宽度计算方法及原理,分析了赣江樟树、丰城、市汊、外洲水文(位)站的最低通航水位、樟树至外洲段的整治线宽度变化,并与Ⅲ级航道整治中设计的参数进行对比分析,得到河床变化对赣江下游的航道整治参数的影响.

| Abstract: | In recent years, the downstream of Ganjiang river is infected by the sand-excavation on the river channel. The river bed and water level decline obviously. The shape of river channel has changed. The waterway regulation parameters have been infected. Based on the analysis of hydraulic characteristics and waterway regulation parameters, this paper calculates the lowest navigable water level for the hydrology station of Zhangshu, Fengcheng, Shicha and Waizhou. The variation of regulation width is calculated and compared with designed results. |

| Keywords: | waterway regulation riverbed degrading the lowest navigable water stage regulation width |
