黄河水下根石探测的浅地层剖面技术

Sub-bottom profiling technology for detecting underwater root-stone in Yellow River

根石探测技术一直是困扰黄河下游防洪安全的重大难题之一。为此,从工程结构、探测条件等方面分析根石探测的技术难点,阐述了适应复杂工况的浅地层剖面技术。通过对其探测成果与人工锥探进行对比分析证明:浅地层剖面技术很好地解决了黄河根石探测的技术难题。

The technology for detecting root-stone is one of the major problems of flood control of the lower Yellow River. For this reason, the sub-bottom profiling technology adaptable to the complicated conditions is expatiated herein with the analysis on the technical difficulties of footstone detection from the aspects of the engineering structures, the detection conditions, etc. Based on the comparison made between the detecting result from the technology and the result from the manual cone detection, it is demonstrated that the technical problems of footstone detection in Yellow River can be better solved by the sub-bottom profiling technology.
