摘要
岩溶分布具有零散性、不连续性和隐伏性等区域性特征,往往给勘察工作带来很大的困难。结合广东省某大桥项目勘察实例,介绍了跨孔CT法,该方法可准确有效地探明岩溶发育情况。通过对比分析,跨孔CT层析成像结果与钻探资料结果具有较好的一致性。
The karst formation and distribution have regional characteristics such as fragmentation,discontinuity and concealment,which make it difficult to prospecting.In this paper,a cross-hole CT method was introduced based on a prospecting case of a bridge project in Guangdong Province,and this method was confirmed to be accurate and effective,the results of cross-hole CT tomography are consistent with the results of drilling data.It is further demonstrated that this technology has high reliability and good application prospect in karst exploration.
