公路隧道下穿饮用水水池的爆破控制

摘要

〔Abstract〕 This project is a new tunnel under the original drinking water tank, because the distance in a straight line, and smaller pool of higher security requirements, which cannot use the traditional blasting ex-cavation. In order to ensure the normal use of the construction of pool, it needs strict control of the same period of detonating explosive charge, and the blasting vibration velocity is reduced to a safe range, and monitoring of blasting vibration velocity ensure that the vibration near the pool under control.%本项目是新建隧道下穿原有饮用水水池，因直线距离较小、且水池安全要求较高，无法使用传统爆破开挖，为保证水池正常使用，施工时严格控制同一段雷管起爆装药量，使爆破振动速度降低到安全范围内，并对爆破震动速度进行监测，确保在水池附近的振动处于可控。
