【摘要】 计算机层析成像简称为CT,是一种利用在物体周边所得到的某种物理量的一维投影数据,经过计算机处理,重建物理特定层面上的二维图像和依据一系列二维图像构成三维图像的技术。本文详细介绍了地震CT探测技术在芭蕉箐隧道中探测应用情况。针对芭蕉箐隧道上、下行线中部均出现坍塌,按照规范的方法对所设计的方案进行了勘测,经过野外数据采集、室内资料处理和地质解释等阶段的工作,本次勘探取得了预期的成果。更多还原

【Abstract】 Computer Tomography referred to as CT,which is taking advantage of an object around a certain physical quantity obtained by one-dimensional projection data,through computer processing,given the level of the physical reconstruction of two-dimensional images and constitutes the basis of a two-dimensional image of the three-dimensional image technology.This paper introduces the application of seismic CT survey method of section arrangement in the Bajiaoqing tunnel.Considering the cracks appeared in the Bajiaoqing tunnel collapse occurred in central of uplink,downlink of Bajiaoqing tunnel,we have surveyed this area according to the designed plan.After the data collecting,data processing,geological interpretation and other meticulous work,anticipated results are achieved from this survey.更多还原
