某混凝土重力坝软弱地基防治措施研究

The Study on the Strengthening Technique for Weak Foundation of the Concrete Gravity Dam

针对某一混凝土重力坝坝基或坝肩存在的风化、软弱夹层及裂缝问题,采用固结灌浆、帷幕灌浆、设置排水设施、内设锚杆相结合的防治方法进行处理,结果表明:该处理方式能合理、有效地保证大坝的正常运行,可为其他类似重力坝地基问题的处理提供技术参考。

In view of the problems of weathering,weak intercalation and cracks in the foundation or abutment of a concrete gravity dam,the prevention and control methods of consolidation grouting,curtain grouting,drainage facilities and anchor bolts are adopted.The results show that the treatment method can ensure the normal operation of the dam reasonably and effectively,and can provide treatment for other similar gravity dam foundation problems For technical reference.
