【摘要】 介绍了在岩溶地区复杂地质条件下,对隧道塌方区进行地震勘探的技术和方法.对于蛟岭隧道塌方区应用弹性波方法,采取一次性布置检波器、多炮激震的观测方式,并运用地震波动力学和运动学特征对地震资料进行解释的方法,确定隧道上方地质灾害体的赋存位置和形态,取得了良好效果.更多还原

【Abstract】 The seismic exploration methods and techniques for tunnel landslide area under complicated geological condition of Karst region are introduced.For the landslide area in Jiaoling Tunnel,elastic wave methods are applied,and one-time seismometers arrangement and multi-shot observation way are used,and the seismic materials are explained by using seismic wave kinematics and dynamics, finally the existence position and shape of the geological disaster above the tunnel roof are determined.Good results have been achieved.更多还原
