盾构施工前方的探地雷达探测模拟试验

Simulated test on ground penetrating radar for shield-driven construction front

紧密结合智能信息化盾构施工辅助系统技术研究,将探地雷达这种高科技的无损探测方法应用到盾构开挖面的地质和障碍物情况探测中,在实验室通过模拟简单的地质情况进行障碍物和地质分层试验.并在盾构基地进行了现场试验,有力地证明了利用探地雷达进行盾构施工前方地质情况探测的可行性.

By integrating intelligent information technology with shield-driven construction aided system, the ground penetrating radar （GPR） is applied to survey geological and obstructive conditions of excavated surfaces. Based on experimental simulations, a geological and obstructive lamination test is carried out. Further-more, a filed test is completed on the shield-driven construction site. It is indicated that the GPR can be feasibly used for surveying geological conditions of shield-driven construction front.
