摘　　要：采用有限元数值模型,结合大坝地质条件、工程材料特性及渗流场分布,对罗田水库大坝的渗流稳定现状进行深入分析,全面评估大坝的安全性能。结果表明,罗田水库大坝在各运行工况下防渗状况良好,浸润线遵循随库水位上涨而提高的规律,渗流量对水库蓄水的影响较小,抗滑稳定安全系数满足规范要求。研究成果为罗田水库大坝的安全运行和管理提供了理论支持和技术帮助,也可为类似工程的渗流稳定安全评价提供有益参考。Using finite element numerical model,combined with the geological conditions,material char-acteristics and seepage field,a deep analysis of the seepage stability status of Luotian reservoir dam is conducted,and the safety performance of the dam is evaluated comprehensively.The results show that the seepage control of Luotian reservoir dam is good under various operation conditions,the saturation line rises as the reservoir water level rises,the seepage flow has little influence on reservoir water stor-age,and the safety factor of anti-sliding stability can meet the requirements of regulations.The research results can provide theoretical support and technical assistance for the safe operation and management of Luotian reservoir dam,and can also provide useful references for the safety evaluation of seepage sta-bility of similar projects.
