TSP作隧道掌子面前方地质预报几例失误原因分析
|
摘要
隧道地质预报是人们关心的技术,但最近使用 TSP-202系统对几个隧道作掌子面前方地质预报出现了大的失误。究其原因是由于:对探测对象的地质特征及地球物理特征认识不清;不了解地球物理资料有多解性;面对复杂的地质对象和地球物理资料的解释,用一种模式编制全自动的地质解释软件:TSP 不适合查找如溶洞、溶管等有限大小物体。因此,应遵循经60 a 以上工作经验总结的正确地应用地球物理技术的规律和方法。
Geological survey forward from working face of tunnel is the technology for engineers to concern.But serious failure happens recently in survey by means of TSP-202 in some tunnels.The failure reason is analized in this paper.In fact,different explanations are made for the data of geophysical survey.If someone is not familiar with complicated geology objects and geophysical features and tries to use one or two models to explain geophysical data with help of intelligent explaining software,the failure would wait for him.TSP is not available to survey the bodies with limited size,as karst caves.The law and way of correct geological and geophysical application must be followed.
