通过对某小型水利工程坝型选择进行实例分析后可知,当其地质条件不具备修筑刚性坝时,采用混凝土面板堆石坝与风化料碾压土石坝方案进行比较,最终选择采用风化料碾压土石坝作为推荐坝型。实例表明风化料碾压土石坝具备取材方便,施工较简单、投资较小、工期较短等特点,希望该分析能为其他类似小型水利工程的坝型选择提供参考。 Through the example analysis of dam selection of a small hydropower project, we can see that when the geological conditions do not have the construction of rigid dam, the concrete faced rockfill dam is compared with the program of weathered earth rockfill dams. Finally, Earth dam as the recommended dam type. The example shows that the weathering material roller compacted rockfill dam has such features as convenient material drawing, simple construction, small investment and short construction period. It is hoped that the analysis can provide a reference for dam type selection of other similar small water conservancy projects.
