通过开展大尺度胶结土坝溃坝模型试验,对胶结土坝在洪水漫顶作用下的流速分布、坝体侵蚀的变化过程进行了分析,以验证胶结土坝漫顶不溃的可能性。试验结果表明:模型填筑胶结土28 d无侧限抗压强度达到4 MPa以上;胶结土坝在最大坝顶水头为... 通过开展大尺度胶结土坝溃坝模型试验,对胶结土坝在洪水漫顶作用下的流速分布、坝体侵蚀的变化过程进行了分析,以验证胶结土坝漫顶不溃的可能性。试验结果表明:模型填筑胶结土28 d无侧限抗压强度达到4 MPa以上;胶结土坝在最大坝顶水头为55 cm、下游坡比1∶2、最大流速达5.6 m/s条件下,漫顶冲刷44 h未发生溃决破坏;漫顶冲刷后下游坝坡最大侵蚀深度为10 cm,平均侵蚀深度仅为1.07 cm;胶结土坝可有效防止洪水漫顶冲刷引发的溃决破坏。 展开更多

The first author proposed the concept of the cemented material dam (CMD) in 2009. This concept was aimed at building an environmentally friendly dam in a safer and more economical way for both the dam and the area downstream. The concept covers the cemented sand, gravel, and rock dam (CSGRD), the rockfill concrete (RFC) dam (or the cemented rockfill dam, CRD), and the cemented soil dam (CSD). This paper summarizes the concept and principles of the CMD based on studies and practices in projects around the world. It also introduces new developments in the CSGRD, CRD, and CSD. 展开更多
