控制爆破开挖对岗南水库新浇混凝土的影响

摘要

为满足水库防汛安全需要，岗南水库新增溢洪道抗滑竖井爆破开挖与混凝土浇筑交替进行。为控制爆破施工对新浇混凝土的危害，本工程通过试验监测应力、应变、质点振动速度、声波等数据，得出了新浇混凝土附件的爆破控制标准，以指导施工，也为类似工程施工提供了参考。%In order to meet the security needs of flood control reservoirs, the Gangnan Reservoir new spillway anti-slide shaft blasting excavation worked with concrete pouring. To avoid breaking fresh concrete, we monitored the stress, strain, particle velocity and acoustic data by test works, and obtained the blasting control standards of fresh concrete accessories to guide the construction, it can provide reference for the similar projects construction.
