非正规垃圾场垃圾体量估算研究

The volume estimation of nonregular landfills

非正规垃圾场主要通过现场开挖钻探和测绘对垃圾体量进行勘查,该方法效率低成本高,出于经济效益考虑,钻孔数量往往较少,地下填埋垃圾体量估算准确性较差,导致后期存量垃圾整治成本提高。为了准确的估算垃圾体量,本文以海南澄迈某非正规垃圾场为例,提出了采用无人机结合工程钻探、探地雷达对非正规垃圾填场垃圾体量进行估算,探索替代钻探和测绘估算垃圾体量的高效方法。结果显示,无人机遥测垃圾总体量最大(13120m3),其次是现场测量及钻探计算的垃圾总体量(12900m3),地质雷达探测的垃圾总体量最小(12300m3),不同方法对垃圾体量估算值之间的变异系数为3.26%。无人机结合工程钻探及探地雷达可替代现场开挖钻探和测绘,在今后类似的填埋场体量估算中具有重要参考价值。

Informal landfill waste volume was mainly explored by site excavation,surveying and mapping,however,to be economic benefit,The numbers of borehole tends to be small,and results in estimation inaccuracy and cost rising of underground solid waste volume.In order to accurately estimate the waste volume,Hainan Chengmai waste site was studied in this paper,unmanned aerial vehicle(UAV)combined with drilling engineering,ground penetrating radar(GPR)were used to assess the volume of solid waste in this informal garbage field,to explore efficient method to evaluate the waste volume.The results showed that the amount of solid waste by uva was largest(13120 m3),followed by excavation,surveying and mapping(12900 m3),and GPR(12300 m3),waste Variation coefficient of different waste quantity was calculated(3.26%).The UAV combined with engineering drilling and GPR can be used as alternative methods for drilling and mapping,which was reference value in similar landfill volume estimation.
