Abstract: Under complex natural condition and as the effect of various inner and outside forces for a long time, earth-rock dam is changing momentarily and safety trouble may generate without obvious pre-warning. Especially, because of careless design, poor-quality construction and unsuitable management, many problems may be encountered for the safety of earth-rock dams built earlier. Combined with geological exploration data and two-dimensional finite element calculation of the dam stability before and after reinforcement, this paper analyzed the current anti-slide stability of Longwangyan dam and presented reinforcement measures, for reference for similar dam.

摘要： 在长期复杂的自然环境条件和各种荷载作用下，土石坝容易产生安全隐患。尤其国内早期修建的土石坝，因为当时条件限制、设计考虑不周、施工质量差、运行管理不当，大坝安全受到严重影响。本文分析了湖北省罗田县龙王岩水库大坝当前的抗滑稳定性，结合地质勘探资料，提出了除险加固的措施，并通过二维有限元计算加固前后的坝体抗滑稳定情况对所采取的措施进行复核，为同类坝的安全鉴定、加固提供借鉴。
