| 摘 要： | 新安江大坝已运行40多年,本文通过对水毁情况、历年泄洪情况的分析,并在冲刷坑理论计算和冲坑系数反推分析的基础上,得出冲坑系数在0.62～1.113之间,即使选用较大的可能冲刷深度,大坝、厂房、开关站等主要建筑物的稳定也能得到保证的结论.同时,提出了减轻泄洪对下游冲刷区影响的工程措施.

| Abstract: | Xin'anjiang dam has been in operation for more than 40 years.The article elicited that the coefficient of scour hole was between 0.62 and 1.113,even if larger possible scour depth,the stability of main buildings,such as dam,powerhouse and switchyard,can be ensured.Further more,the paper put forward some engineering measures to alleviate flood discharge influence to scour area. |
