随着科技的不断进步,物探技术越来越多地应用到水工混凝土质量的检测中。本文介绍了在某水闸安全鉴定过程中,采用弹性波CT技术对闸墩、底板等体积较大、且位于水下的老旧混凝土的内部质量进行检测,并通过钻孔勘探、强度试验以及压水试验等方法进行综合分析,取得了较好的效果,对今后类似工作有一定的借鉴作用。 With the continuous improvement of science and technology, geophysical techniques are increasingly applied to the detection of hydraulic concrete quality. In this paper, we introduce the testing of internal quality of old concrete, such as sluice pier and bottom plate, which is bulky and underwater under the safety assessment of a sluice by using elastic wave CT technique. Through drilling exploration, strength test and pressure Water test and other methods to conduct a comprehensive analysis, and achieved good results, for some similar work in the future have a reference.
