毛竹冬笋并行电法探测可行性研究与观测系统优选
|
摘要
浅埋冬笋与其生长区域土层之间存在电性差异,这是电法探测冬笋生长位置、大小等的岩石物理基础。使用米字形和圆形两种不同观测系统对毛竹冬笋进行并行电法数值模拟试验研究,结果表明,采用两种观测系统在毛竹冬笋正上方利用并行电法探测冬笋空间展布位置是切实可行的,且米字形观测系统的探测效果更佳,其有效探测深度约为0. 30 m,对于埋深约0. 20 m的冬笋探测效果尤为显著。现场测试充分验证了米字形观测系统并行电法对冬笋的探测效果。该研究结果可为冬笋类植物根系探寻提供一种新的手段。
There are electrical differences between the shallow buried bamboo shoots and the soil layer in the growing area,which lays a rock physics foundation for the electric exploration to detect the growth position and size of the winter bamboo shoots. Parallel electric numerical simulation tests of bamboo shoots were carried out with two different observation systems: the Union Jack shape and the circle shape. The results showed that it was feasible to use the parallel electric method to detect the spatial spreading position of winter bamboo shoots above them based on the two observation systems,and the detection effect of the Union Jack shape observation system was better. The effective detection depth was about 0. 30 m,and the detection effect was especially significant for winter bamboo shoots with a buried depth of about 0. 20 m. The field tests fully verified the detection effect of parallel electrical method of the Union Jack shape observation system on winter bamboo shoots.This study could provide a new method for the root system exploration of winter bamboo shoots.
