    摘要:

    为了避免福岭采石场爆破施工对周边民房的影响,布设4个测试点,对不同药量及距离产生的爆破振动给附近民房带来的影响进行监测和分析,得到了振动衰减关系及该采石场爆破施工对附近民房影响的安全距离。当保护对象距离为200 m时,96 kg药量,振动速度为0.45 cm/s,达到土坯房和毛石房屋容许振动的上限值。

    Abstract:

    To avoid the impact of the blasting construction in Fuling quarry on the surrounding residential houses, a total of four test points were set up, and the influence of blasting vibration with different blasting charges and distances on nearby houses was monitored and analyzed. The vibration attenuation relationship and the safe distance of the quarry blasting construction for nearby residential houses were obtained. When the distance from the protected objects is 200 m, the blasting charge is 96 kg, and the vibration velocity is 0.45 cm/s, the upper limit value of the allowable vibration of the adobe house and rubble house is reached.
