摘　　要：作为引江济太工程的一部分,新沟河整治工程在2014年开始实施。基于2013～2014年的太湖水系湖网水文站实测资料,通过河湖耦合的一维水沙数学模型计算新沟河整治工程前后水位和水流泥沙冲淤变化,进行新沟河河网水沙动力分析;通过二维水沙数学模型计算新沟河工程前后的水位、流场及河道的冲淤变化,进行工程整治效果预测分析并提出优化建议。实施新沟河整治工程后,新沟河水系河网的主要功能是排涝,应急情况下也能通过新沟河向太湖调水以改善水质。As part of the Yangtze River to Taihu Lake Water Transfer Project, Xingou River regulationproject was initiated in 2014. Based on the measured data in Taihu river network during 2013-2014, 1D lakeand river coupling model was applied to water level and sediment transport calculations of the Xingou rivernetwork; 2D hydraulics and sediment transport model was applied to water level, flow field and sedimentcalculations of the project, and suggestions and optimization of the regulation scheme were brought up. Mainfunctions of Xingou River network was flood routing and sewage discharge. It also provided a water transferchannel in emergence, which would transfer water to Taihu Lake improving water quality of Taihu Lake.
