【摘要】 地球物理勘探方法应用于隧道掘进中的超前预报工作,不仅具有快捷、准确的特点,而且还能进行实时处理与显示。以湖南境内常(德)吉(首)高速公路29合同段小陂流隧道的超前预报为例,通过TSP203探测,可以及时、详细、准确地了解开挖掌子面前方的地质情况,从而为施工单位合理安排施工作业进度、减少工程隐患提供科学依据。更多还原

【Abstract】 The application of geophysical technique to advanced prediction during tunneling has the advantage of high speed and accuracy.In addition,all the data obtained,can be dealt with and displayed in time.The Xiaopiliu Tunnel at 29th Section of the Changde-Jishou Expressway in Hunan is given as an example.By this way we can be accurately informed of the geological condition before tunneling.Such information is very important in arranging the tunneling method and reducing the risk of work.更多还原
