跨孔弹性波CT技术在岩溶地质勘探中的应用

Application of Cross-hole Elastic Wave CT Technology in Karst Geological Exploration

岩溶地质对建筑项目的结构设计、施工以及运营均会造成严重影响,并且常规地质勘探方法成本高、效率低、覆盖面窄,难以适应当前高要求、严标准的施工状况。基于某隧道工程,采用跨孔弹性波CT技术对场地进行了岩溶地质勘探,将跨孔弹性波CT测试与钻孔资料进行联合分析,综合解译、去伪存真,得到了较为准确的地质解释成果。试验表明,跨孔弹性波CT技术在岩溶勘探中准确度较高,建议推广。

Karst geology has a serious impact on the structural design,construction and operation of construction projects,and conventional geological exploration methods have high cost,low efficiency and narrow coverage,which are difficult to adapt to the current high requirements and strict standards.Based on a tunnel project,the cross-hole elastic wave CT technology was used to carry out karst geological exploration on the site.The cross-hole elastic wave CT test and borehole data were jointly analyzed,and the more accurate geological interpretation results were obtained.The test shows that the cross-hole elastic wave CT technology has high accuracy in karst exploration and is recommended for promotion.
