坚硬爆破坝料碾压试验孔隙率偏大原因分析

Analysis on the cause of larger porosity in hard blasting dam material rolling test

土石坝工程中爆破坝料填筑多以孔隙率控制,坝料碾压试验是坝体施工前的关键环节,它直接关系工程施工质量、运行安全和建设成本,因此相关施工参数需通过多次试验修正。本文通过分析吉音水利枢纽爆破坝料碾压试验孔隙率偏大的原因,提出相应的解决方法和措施,为同类工程建设提供借鉴与参考。

Blasting dam material filling in earth-rock dam projects is mostly controlled with porosity.Dam material rolling test is a key link before dam construction.It is directly related to engineering construction quality,operation safety and construction cost.Therefore,related construction parameters should he corrected in many experiments.In the paper,cause ol larger porosity in blasting dam material rolling lesl ol Jiyin water conservancy hub is analyzed,and corresponding solution and measures are proposed,thereby providing reference lor constructing similar projects.
