| 摘 要： | 拟建浙江三门核电厂人工边坡长约180 m，边坡最高约53 m。该边坡坡脚与拟建的核岛、常规岛或其他重要建（构）筑物之间的距离仅为50多米，故需对边坡的稳定性进行评估。采用工程地质类比法、赤平极射图解分析法及MARC有限元对拟建边坡进行稳定性评价，认为边坡总体开挖角不大于60°时，整体上是稳定的。建议实际开挖坡角55°左右，采用分级放坡，边坡阶段高度可按8.0～10.0 m考虑，马道宽度3.0 m左右，并设截水沟等排水设施。

| Abstract: | A nuclear power plant is to be constructed in Sanmen county of Zhejiang Province, where there will be a rocky slope with length of about 180 m and the maximum height of about 53 m. The distance between the slope toe and the nuclear island is about 50 m; so the stability of the slope should be evaluated. This paper applied engineering geological analogy method, stereographic projection method and finite element program MARC to evaluate the rocky slope stability. It is concluded that the slope is overall stable when the slope angle is smaller than 60°. The slope angle 55°or so is suggested for practical engineering; and grade sloping should be carried out with the height of every segment 8.0-10.0 m and the width of berm about 3.0 m. |
