| 摘 要： | 峡江水利枢纽工程岩体完整性差、抗冲能力较弱,应采取相应工程防护措施。对11闸段墩进行计算分析后得知,11闸段墩的抗滑稳定不满足规范要求。为此,采用非线性数值方法,对11闸墩的深层抗滑稳定安全系数进行校核,并运用有限元软件SAPTIS对11闸段墩段深层抗滑进行非线性有限元分析。根据分析结果,针对该缺陷提出加厚底板方案和锚筋桩方案,并得出结论——两种方案都能够满足抗滑稳定性要求。

| Abstract: | The Xiajiang hydro-junction project is featured with bad rock integrity and weak anti-scouring ability,so protective engineering measures shall be taken.Analyzing the No.11 sluice-pier,we know that the anti-sliding stability of No.11 sluice-pier cannot meet the requirements of relevant specification.Adopting the nonlinear numerical method,we check the safety factor of deep-layer anti-sliding stability of No.11 sluice-pier and conduct the nonlinear finite element analysis of it by SAPTIS.According to the analysis results,we propose two schemes,i.e.,thickening the bottom slab and arranging systematic anchor piles,both of which can meet the requirements of anti-sliding stability. |
