坝陵河大桥基础工程施工岩溶地质探测及预报

Karst Geology Detection and Prediction for Construction of Foundation Works of Baling River Bridge

坝陵河大桥基础工程岩溶非常发育。针对东索塔、东锚碇基底及西锚洞工程岩溶发育情况,分别采用高密度电法、地质雷达和HSP声波反射法进行岩溶探测。实践表明,以上几种方法的综合应用效果较好,对工程施工起到了指导作用。

The karst at the foundation works of Baling River Bridge is very developed. In the light of the karst development situations at the foundations of the east tower, east anchorage and west anohorage tunnel of the Bridge, the karst was detected respectively by the high-density resistivity , geologic radar and HSP sonic wave reflection methods. Practice proves that the effect of comprehensive application of the above-mentioned methods is sound and the application of the methods can play a good guidance role in the construction of the foundation works.
