| 摘要: |
| 为解决石泉大坝在校核洪水位岸边非溢洪坝段坝踵应力超限问题，采用了预应力锚索加固方案。在左右非溢洪坝段共布置30个锚固孔，单孔张拉力为5880kN，孔最深达70m。在施工中建立了一套完整的全面质量管理体系，从而确保了加固质量，使大坝防洪标准提高到千年一遇。 |

| Abstract: |
| For resolving the superduty stress at the dam toe of nonoverflow dam section thescheme of prestressed cable anchorage were adopted by arranging 30 anchorage pores onthe two sides of the non-overflow dam section,and the single pore tension is 5 000kN,themaximum depth is 70m. Also establish a perfect quality management system during theconstruction. All these make the remedy quality firmly and raised the floodproofing standard to 100-year flood. |
