AbstractThe practica of overseas sediment control dam of debris flow has undergone above hundred years. At present, the theoretical basis for designing sediment control dam -- dynamic theory of debris flow has been prelimninarily established and is being perfected. The characteristics of the overseas sediment control dam of debris flow are: 1.the retaining step-dams for controlling debris flows have a extensive use; 2. the lattice retaining dams are being spreaded; 3. the new-type retaining structures are constantly springing up; 4. the high dams are employed in order to protect the big cities from the disaster of debirs flow; 5. the standard for calculation load of the controlling engineerings of debris flow was laid down; 6. the sediment control dam of debris flow have been looked on as the measures for protecting and ameliorating environmnet in a few countries; 7. the engineerings for dissipating energy of sediment control dam of debris flow are developing. The contents of calculation of overseas sediment control dam of debris flow include the calculations of strengh (being mainly impact pressure), acceumulation, geometry and hydraulic.
Other Abstract回顾国外泥石流挡坝工程实践的历程,分析工程实践的特点、计算内容与方法。国外许多学者从事泥石流挡坝工程的试验研究,比如对挡坝型、结构、稳定性、计算方法和防治效益等方面的模型试验。
