多数隐蔽的隧道、地下防空洞的修建都会面临施工过程中的地质勘察与预测等问题。针对地下工程开挖过程中的地质灾害特点,基于弹性波三维空间传播理论,通过三维仿真建模和分析,应用现代计算机和无线通讯技术研究设计无线分布式信号采集系统;应用地震波共反射面元叠加、偏移成像和相控阵等技术实现对国防工程地质灾害的无线分布式三维探测与三维成像,对工作面前方地质情况和不良地质体高精度准确定位,从而将实现超前预报的三维空间化与可视化,为工程动态设计和信息化施工提供可靠依据。
Most of the concealed tunnels and underground shelters will face such problems as geological survey and prediction during the construction. According to the characteristics of geohazards during excavation of underground engineering, based on the theory of three-dimensional elastic wave propagation, the wireless distributed signal acquisition system is designed and studied by using modern computer and wireless communication technology through three-dimensional simulation modeling and analysis. Superimposed, offset imaging and phased array technology to achieve the three-dimensional wireless distributed detection and geological imaging of national defense engineering geological disasters, accurate positioning of the geological conditions in front of the working face and poor accuracy of geological bodies, so that will achieve three-dimensional spatial prediction And visualization, to provide a reliable basis for engineering dynamic design and information construction.
