摘要
丹江口大坝老混凝土拆除 ,技术难度大 ,安全要求高。通过对 4种方案的比较研究 ,选择钻孔爆破方案。在实际施工过程中 ,对爆破方案进行了优化 ,取得了良好的爆破效果。
Due to the technologically high difficulty and requirements in demoloshing the previously hydrated concrete at Danjiangkou Dam, the optimum drilling and blasting pragram was selected after four programs being compared.
