摘要
在穿黄工程线路比选试验成果基础上,通过实体模型试验,进一步研究了中线隧洞方案和下2线渡槽方案在河道不同缩窄宽度条件下,对河势、水位、流速及河床冲淤的影响,认为中线隧洞方案河道缩窄至3.0km和下2线渡槽方案河道缩窄至3.8km均可行。
By physical model tests,the influences of the middle?line tunnel scheme and the lower line aqueduct scheme on river regime, water level, velocities and river?bed scour under different river narrowing widths were further studied on the basis of comparison and initial selection test of Yellow?River ?crossing works. The test results showed the middle?line tunnel scheme with river width 3.0 km and the lower?line Ⅱ aqueduct scheme with width 3.8 km are feasible.
