黄河下游堤防工程隐患探测技术与应用

The geophysical detection technology and application to hidden troubles of dikes in the lower reach of the Yellow River

黄河下游堤防是各个时期逐步修筑而成的,各次修筑质量参差不齐,加上历史决口堵复时使用的物料腐烂和有害动物破坏,近年来水量减少、断流增加,河道淤积严重,水流散乱,河势极其不稳,致使堤防工程形成众多险点隐患.本文根据黄河下游堤防工程特点,成功地运用高密度电阻率法技术探测堤防隐患,取得了较好的探测效果,为堤防工程的检测和监测提供了可靠的资料.

The embankment in the lower reach of the Yellow River was constructed stage by stage in history. There are a good deal of construct quality problems, for instance the materials to burst stifled in the last time were decomposed or destroyed by baneful animals. It has many hidden troubles in recent years such as river-way fill up, current messy and unstable river circumstance because of the decreasing river water and the water turnoff. This paper introduces the multi-electrode resistance method technology. Which can be used to detect hidden trouble in the lower reach of the Yellow River and obtained preferable results. It offers reliable data to check and inspect engineering interior quality of this area.
