大型滨海电厂排水明渠研究与设计

Study and design for large-scale open drainage channel of coastal power plant

基于滨海电厂排水明渠排水流量大、排水不间断且受外海潮汐影响的情况,对不同潮位条件下,不同明渠纵横断面的明渠流速、水位开展了物理模型与数学模型研究,并结合明渠位于寒冷地区及明渠基础为近期吹填土的特点,进行了明渠纵横断面设计、护砌结构设计及地基处理设计,以满足电厂循环冷却水排放的使用要求。

Coastal power plant based on large drainage flow, continuous drainage and tides affected by the situation. In this paper, to meet the power plant cooling water discharge requirements,considering the features of cold regions,new reclama- tion soil,the study of flow velocity and water level under different vertical and horizontal channel＇s cross-section has been done through physical model and mathematical model according to different tidal conditions, and then the cross-section, revetment structure and foundation treatment of drainage channel has been designed.
