某水库大坝安全复核及除险加固方案分析

Analysis of Safety Review and Reinforcement Scheme of a Reservoir Dam

小胡楼水库大坝在长期使用过程中出现了坝坡破损、渗流不满足安全要求以及其他安全隐患,亟需采取除险加固工程措施。经过方案比选,采用劈裂灌浆的方式进行防渗加固,具有造价低、工艺成熟等优势;上游坝坡仍采用干砌石护砌,下游坝坡进行培厚加固处理,并重建下游排水设施。可为类似工程除险加固提供参考。

During the long-term use of the Xiaohulou Reservoir Dam,there have been problems such as damaged dam slope,seepage that does not meet safety requirements,and other safety hazards.It is urgent to take measures to eliminate risks and reinforce the dam.After scheme comparison and selection,the method of splitting grouting is adopted for anti-seepage reinforcement,which has advantages such as low cost and mature technology;The upstream dam slope is still protected by dry masonry,while the downstream dam slope is thickened and reinforced,and downstream drainage facilities are rebuilt.It can provide reference for similar engineering risk removal and reinforcement.
