现代船舶水动力不断侵蚀通航运河水道边界,引起运河航道的日益恶化萎缩,水运界虽然普遍采取了传统的护底与护岸的方法作为对策,但至今国际上尚未能够防治这类水动力的破坏作用。本文在江苏通扬运河航道实测船舶水动力、泥沙运动以及历次航道普查等资料的基础上,研究这类运河航道在自然界中的发育过程,并试图建立在现代船舶水动力条件下平原水网区闸化后通航运河的一套演变模式,从而探索因势利导的整治途径。
The modern ship hydrodynamics continuously erodes the navigable boundary of the canal watercourse and causes the deterioration of the canal fairyland to decline. Although the traditional method of protecting the bottom and the revetment has been taken as a countermeasure, the destructive effect of such hydrodynamics has not yet been prevented in the world . Based on the data of hydrodynamic, sediment movement and previous census surveys in the Tongyang Canal Channel in Jiangsu Province, this paper studies the development process of these canals in nature and attempts to establish a water network in the modern hydrodynamic conditions of the plain water network After the sluice of the navigable canals, a set of evolutionary modes, so as to explore the ways of rectification.
