综合物探技术在大宁调蓄水库防渗墙检测中的应用
|
摘要
北京市南水北调配套大宁调蓄水库工程是解决北京市防洪和调蓄问题的重要工程之一。防渗墙是大宁调蓄水库的主体工程,所以对防渗墙的检测是工程的重要环节。针对防渗墙的检测这一特点,突破传统的高密度电法、地震映像法等物探检测方法,通过试验研究,决定采用超声波测井和孔内电视相结合的方法进行检测。探测的成果真实客观地反映了防渗墙的内部情况,效果良好,为设计提供了科学的数据。两种探测方法在大宁调蓄水库防渗墙的成功检测,表明随着国内外科学技术的快速发展,综合物探技术在各种工程勘察中将有更大的发展空间。
Beijing Daning water reservoir project of south-to-north water transfer project is very important in Beijing,which solves flood control and water storage problem of Beijing city.Diaphragm wall is the main project of Daning storage reservoir,so the impervious wall detection is an important part of the project.As to detecting the diaphragm wall,through test and study,break through the traditional geophysical exploration methods,such as high density electrical method,seismic imaging method and so on,decided to adopt the ultrasonic logging and borehole TV method to detect it.The outcome data of detection responded the condition of inner impervious wall objectively.It works out well providing the scientific data to the designers.Two kinds of exploration methods are successfully applicated to seepage prevention wall of Daning water reservoir,which shows that with the rapid development of science and technology at home and abroad,the comprehensive geophysical technology will have a wide development in various engineering.
