硐室爆破技术在山区路基开挖及料场开采中的应用

Application of Chamber Blasting Technology in Excavation of Subgrade and Exploitation of Material Yard in Mountainous Area

山区公路工程路基及料场开采施工中,由于受地形、地质、水文、工期、炸药运输、储存等条件的影响,应合理采用硐室爆破技术。硐室爆破是一种传统的爆破施工方式,与其他爆破方式对比,硐室爆破施工具有设备投入小、成本低、一次爆破石方量大、工期短等特点,往往发挥不可替代的作用。山区工程施工合理的应用硐室爆破方法,应用工程较多,精心设计,严格施工,从技术、成本、工期等分析,具有一定的优势。

During the exploitation and construction of subgrade and material yard of mountainous highway engineering,chamber blasting technology should be reasonably adopted due to the influence of terrain,geology,hydrology,construction period,transportation and storage of explosives.Chamber blasting is a traditional blasting construction method.Compared with other blasting methods,chamber blasting construction is characterized by small equipment investment,low cost,large quantity of primary blasting stones and short construction period,and often plays an irreplaceable role.There are many projects using chamber blasting method in mountainous engineering construction.According to the analysis of technology,cost and construction period,the chamber blasting method has certain advantages.
