| 摘 要： | 大湾电站调压井工程原设计为竖井方案，井筒直径16m，由于地处强风化的破碎岩体中，大跨度的井筒尤其穹顶部位，难于开挖成型，施工安全、质量也难以保证。经认真研究，将原方案调整为螺旋式调压井，有效地避开了强风化破碎岩体。本文对此加以介绍。

| Abstract: | Dawan Hydropower Station surge shaft project is originally designed into vertical shaft.The shaft diameter is 16m.Since the project is located in highly weathered crushing rock,it is difficult to excavate and shape shaft with large span,especially in dome area.The construction safety and quality cannot be ensured.The original plan is adjusted into spiral surge shaft after careful research,thereby effectively avoiding highly weathered crushing rock.The condition is introduced in the paper. |
