摘　　要：为解决目前工程地震勘探中震源能量较弱问题,采用可控震源小型化的方法,将可控震源引入工程地震勘探领域,以提高工程地震勘探的精度和准确性。可控冲击震源工程试验表明:可控冲击震源较锤击震源能量强,可用于高分辨工程地震勘察,探测长度可达180 m;在Ⅲ级围岩地质条件下,可控冲击震源可替代炸药用于长距离超前地质预报。In order to solve the problem of weak source energy in current engineering seismic exploration,the method of miniaturization of vibroseis is used to introduce vibroseis into the field of engineering seismic exploration to improve accuracy of earthquake exploration.The engineering experiment of controllable shock source shows that the energy of controllable shock source is stronger than that of hammer source,which can be used for high resolution engineering seismic survey and the detection length can reach 180 m.Under the geological conditions of gradeⅢsurrounding rock,vibroseis can replace explosives for long-distance advanced geological prediction.
