| 摘 要： | 为分析峡江水电站泄洪闸#11闸室的稳定性,将锚筋桩抗剪能力等效至潜在滑动面,采用非线性有限元方法计算获得了不同方案下闸室的深层抗滑能力。结果表明,不同方案下#11闸室的滑动破坏模式基本一致,但抗滑能力有所不同,只有将A、B护坦连成整体且将A区护坦中后部锚固加密至3Φ36mm@2×2.5m以上时闸室的深层抗滑能力才满足现行规范要求。

| Abstract: | In order to ensure the anti-sliding stability of No. 11 sluice of Xiajiang hydropower station, different design plans are analyzed by using nonlinear FEM method with shear bearing capacity of anchorage pile equivalent to potential sliding surface. The results show that the sliding mode of each design plan is basically same although the anti-sliding ability is different; the anti-sliding stabilities of the plan combining A with B apron and anchoring sparsely in the central and rear area of A apron can not meet requirements of design specification for sluice until anchoring density is greater than 2 m×2.5 m. |
