近几年,在市区和建筑物附近开挖隧道的工程增加了,而爆破施工法有震动、噪声、飞石等问题,所以,开展了低震动爆破施工法和无爆破施工法的研究。几年来发表了很多无爆破施工法的文章。如利用生石灰吸水膨胀性破碎剂破岩的施工法,用油压把楔子 In recent years, there has been an increase in the excavation of tunnels in urban areas and buildings, while the blasting construction method has problems such as vibration, noise and fly-stone. Therefore, the research on low-vibration blasting construction method and non-blasting construction method has been carried out. Over the past few years published a lot of blasting construction method article. Such as the use of lime absorption of water expansive broken rock breaking construction method, with hydraulic wedge
