摘　　要：随着经济的发展和基础设施建设的不断推进,在部分河道内曾进行过较大强度的挖砂采石活动。目前随着生态和环保意识的不断增强,无序开采活动基本绝迹,但已造成的影响短期内却不会消除。长江上游红灯碛滩挖砂采石影响凸显以后航道整治建筑物功能减弱,航道条件恶化,威胁通航安全。在航道维护中通过工程措施恢复原有航道整治建筑物功能,防止河段航道出浅碍航,取得较好的效果,并为后续进一步航道治理奠定了基础。With the development of economy and continuous advancement of infrastructure construction,there have been more intensive sand and quarrying activities in some rivers.At present,with the increasing awareness of ecology and environmental protection,disorderly mining activities have basically disappeared,but the impact will not be eliminated in short term.The impact of sand quarrying of Hongdengqi Beach in the upper reaches of the Yangtze River is reflected in weakened function of the channel regulation building and deteriorating waterway conditions,which threaten the safety of navigation.In the channel maintenance,the original function of the channel regulation building will be restored by taking engineering measures to prevent the shallow channel of the river section hinder navigation,which has achieved good results and laid a foundation for further improvement of the channel.
