岷江长滩河段航道整治试验研究

Model test of regulation works for the navigation channel of Changtan reach in Mingjiang river

根据岷江长滩滩险碍航的特点,采用卵石动床模型进行整治方案研究,取得了良好的效果.本文简要介绍了长滩河工模型的模型设计、验证及方案试验情况.该工程现已竣工,经过几个水文年的检验,滩险航道的通航条件得到彻底改善,整治效果好,已通过工程验收,该工程被评为优良工程.

According to the characteristics of the shoal and rapids lying in Changtan reach in Mingjiang river and obstructing the navigation channel, a model test was conducted to study the regulation schemes and took good effects. In the paper, the model design, verification and testing process of the Changtan reach engineering are introduced in brief. The project has been already accomplished. By several hydrographic years, verification, the navigation conditions have been greatly improved, and the regulation effects are satisfying. The project has passed the engineering checks and been appraised as superior.
