摘　　要：在高山峡谷地区修建堆石坝,将正常或非常溢洪道直接布置在坝顶上,具有简化枢纽布置、节约工程造价和方便施工等优点。通过对堆石坝坝顶溢洪道带有地锚的泄槽底板进行稳定分析和内力计算,得出地锚参数与其所受各力之间的关系式和安全系数表达式,为今后的工程设计提供理论计算方法,经实例验证该方法是可行的。To build the rock-fill dam in the valley between high mountains, the normal or extraordinary spillway is often arranged on the crest of dam directly, which can simplify the control structure arrangement, save project cost and is easy to construct. The stability analysis and stress calculation for the chute bottom slab with anchorage of crest spillway of rockfill dam gives the anchorage parameters, relationship of various forces and its safety coefficient expressions, which provides the theoretical calculation method for the future project design. The practice showed that this method is feasible.
