基于综合物探技术的铁路路基岩溶探测方法研究

Study on Karst Detection Methods of Railway Subgrade Based on Integrated Geophysical Prospecting Technology

传统铁路路基岩溶探测方法直接对地质剖面进行绘制,未对岩石物性参数进行统计,造成传统方法探测效率低。提出基于综合物探技术的铁路路基岩溶探测方法研究。采集多组石料样品,对岩石物性参数进行统计,将采集来的参数传输到计算机中利用软件进行地质剖面绘制,基于综合物探技术对不同岩石和土壤进行勘探,将勘探结果补充在地质剖面上,从而实现基于综合物探技术的铁路路基岩溶探测,设计对比实验,实验结果表明该研究方法具有更高的探测效率。

The traditional karst detection method in railway subgrade directly draws the geological section without statistics of rocks’physical parameters,resulting in low detection efficiency.Based on the integrated geophysical prospecting technology,the karst detection method in railway subgrade is put forward.By collecting many groups of rock samples,their physical property parameters were recorded and then submitted to the computer software for geological section drawing.With the integrated geophysical prospecting technology,different rocks and soils were explored,and the exploration results were then added to the geological section to realize the karst detection of railway subgrade based on the integrated geophysical prospecting technology.A comparative experiment was also designed,and the experimental results showed that the method has higher detection efficiency.
