摘　　要：导流防沙堤的平面布置会直接影响沿海港口的港池、航道或者核(火)电厂取水明渠泥沙淤积的强度和范围。针对沙质海岸波流共同作用下的导流防沙堤平面优化布置问题,建议导流防沙堤的走向与强浪向反方向的夹角应该小于90°,以45°～60°为宜。辽宁红沿河核电厂取水口局部泥沙物理模型试验结果支持这一建议。The layout of breakwaters will affect directly the magnitude and distribution of sedimentation within harbor basin ＆ entrance, intake forebay of nuclear （or thermal） power plants and other coastal infrastructures. As to the optimization of breakwater layout on sandy coasts, we suggest that the extension of the dike shall have an angle of less than 90° with the reverse direction of dominant wave directions, normally 45°-60°, which has been proved with physical model experimental results on sedimentation at the water-intake mouth of Liaoning nuclear power plant.
