瞬态瑞雷波及地震映像法在海堤检测中的应用

Applications of Methods of Transient Surface Wave and Seismic Image to the Inspection of Sea Wall

海堤检测中 ,查明填石层的厚度是最关键的问题 ,而查明填石层的横断面形态又是最困难的问题。在广东某海堤检测中 ,我们应用瞬态瑞雷波法查明填石层的厚度收到较好效果 ,应用地震映像法查明填石层横断面两翼展宽和底宽也收到较好效果。应用该 2种方法再结合钻探和钎探 ,海堤横断面形态的确定就可以迎刃而解了。

In the inspection of seawall the key point is to ascertain the thickness of fill stones and the most difficult problem is to ascertain the cross section of fill stones.The method of transient surface wave was used to ascertain the thickness of fill stones for the inspection of certain sea wall in Guangdong province,which got the good effect.The method of seismic image was used to ascertain the width of the cross section of the fill stones.Through the combination of the said methods with the drilling and bit inspection the determinations of the shapes for the cross sections of sea wall are solved.
