摘　　要：在高山峡谷河流上修建土石坝,若溢洪道布置在岸坡上,开挖工程量会很大。为节约工程造价可将溢洪道直接布置在坝体上。坝体溢洪道的泄槽一般都比较陡,为确保其稳定性现对泄槽底板进行多层水平锚筋加固。通过对泄槽底板的稳定分析得出锚筋的数量和长度与其受力的关系式,为今后工程设计提供理论依据。When building earth-rock dam in river of high canyon,the excavation quantities of spillway will be very large.For saving project cost,the spillway can be directly plan on the dam,the chute of the spillway is generally more steep.In order to ensure its stability,to strengthen the base plate of spillway with multilayer level anchor rods is necessary.Through the stability analysis for the base plate,we can also obtain the relationship formula between the numbers and length of anchor rods and the stress.It can provide a theoretical basis for the future project design.
