摘　　要：在高地震烈度区的岩石高边坡抗震安全评价需要大规模数值计算,而现有商业软件无法有效解决这类复杂的工程问题,因此,本文开发了解决岩石高边坡接触稳定性问题的对等架构并行计算程序,并应用于泰山公司抽水蓄能电站上水库左岸边坡的静力和动力稳定性评价。在数值建模过程中,将岩石边坡滑块体、地质结构面、库水作用以及近场地基作为岩石高边坡动力接触系统。在稳定性安全评价中结合了有限元法、极限平衡法和接触算法,考虑影响高边坡稳定性的多种复杂因素,通过计算特定滑动面的安全系数或安全系数时程,基于现行水电工程水工建筑物抗震设计规范,完成了岩石高边坡稳定性评价,回避了求解复杂岩体材料非线性的问题。计算结果显示,所开发的程序具有较高的并行计算效率,对解决复杂岩石高边坡稳定问题具有显著的优势。Large-scale numerical simulation is desirable in the stability evaluation of high rock slope in high earthquake intensity area,but the existing commercial software can not effectively solve these complex engineering problems. Therefore,a parallel program with a peer-to-peer architecture was developed and applied to the stability evaluation of the left bank slope of upper reservoir of Taishan pumped storage power station. Included in the modeling as the dynamic contact system are the rock slope slider body, geological structural surface, reservoir water effect, and near-site foundation. The computation mixed finite element method, limit equilibrium method and contact algorithm, and the output include the safety factor and its time history of a specific sliding surface. The stability evaluations of the high rock slope satisfies the current seismic design code of hydraulic structures, thus avoiding nonlinearity of complex rock material. The computing results show that the program is highly efficient and advantageous in solving the stability problem of complex high rock slope.
