水库大坝的渗流稳定状态是水库大坝安全管理至关重要的部分,同时是水库大坝安全评价与除险加固的基础。为保证水库大坝的安全运行,针对水库大坝渗流稳定计算分析问题,以某水库均质土坝为研究对象,采用Fortran程序建立非线性有限单元的模型,对水库大坝渗流稳定计算。结果表明,各工况下大坝下游坝坡逸出点的最大水力坡降均小于允许坡降,浸润线均低于于下游反滤排水设施,大坝渗流安全;各工况下大坝各滑带的抗滑稳定安全系数,均大于规范允许值,满足规范要求。研究成果对其他水库大坝的安全评价与除险加固有指导意义。
Finite Element Analysis of Seepage Stability in a Reservoir Dam Based on Fortran Program
The steady state of seepage in reservoir dams is a crucial part of reservoir dam safety management,and it is also the basis for reservoir dam safety evaluation and risk elimination and reinforcement.In order to ensure the safe operation of the reservoir dam,aiming at the problem of calculation and analysis of the seepage stability of the reservoir dam,a homogeneous earth dam of a certain reservoir was taken as the research object,and the Fortran program was used to establish a nonlinear finite element model to calculate the seepage stability of the reservoir dam.The results show that under each working condition,the maximum hydraulic gradient at the escape point of the downstream dam slope is less than the allowable gradient,and the infiltration line is lower than the downstream reverse filter drainage facility.The seepage of the dam is safe;under each working condition,the maximum hydraulic gradient of the dam is The anti-skid stability safety factor of the sliding belt is greater than the allowable value of the specification and meets the specification requirements.The research results have guiding significance for the safety evaluation and risk elimination of other reservoirs and dams.
