摘　　要：定向爆破堆石坝坝体材料不均一,孔隙率不均匀,坝体变形难以收敛,防渗系统易破坏,常出现坝体渗漏严重等病险情。结合典型工程实例,对我国定向爆破堆石坝的病害特点及加固技术进行了研究,爆破堆石坝抛投填筑后,应根据坝体病害特点,对坝体结构整形加固,并采取有针对性的防渗加固措施,以确保水库大坝安全。For the directed blasting rockfill dams,the dam body materials are usually of big non-uniformity and non-uniform porosity. Thus,the dam deformation is difficult to converge and the seepage prevention system can be easily destroyed,which could cause illnesses such as serious seepage flow. With the analysis of typical engineering examples,the illness characteristics and reinforcement technology of directed blasting rockfill dams are discussed. To ensure the safety of the reservoir,reinforcement measures on the dam structure and the seepage prevention system should be taken according to the illness characteristics of the dam body.
