微动谱比法辅以钻探校对在历史遗留固体废物堆存区中的应用研究

Application and research of microtremor horizontal-vertical spectral ratio combined with drilling proofreading in historical solid waste storage area

矿区固体废物堆存区有大量废物矿渣堆存,存在高势能的人造泥石流和溃坝危险源可能性较大。为避免危险,本文采用微动谱比法选取广西3个历史遗留固体废物堆存区开展物探勘测工作,并结合少量钻探进行反演参数校对,得到不同面波波速区域、不同面波波速的微动谱比法反演参数最佳选择。结果表明,该区的低面波波速区,横波表层速度优选较小值(通常小于200 m/s);中等面波波速区,横波表层速度选择偏中等值(250 m/s左右);高面波波速区,横波表层速度优选较高值(通常为300 m/s以上),主要针对覆盖层较薄,占比小,基岩较完整区域。

The"14th Five-Year Plan for the Development of Engineering Survey and Design Industry"and the"14th Five-Year Plan for the Development of Guangxi Engineering Survey and Design Industry"point out that the concept of green development should be integrated into the whole process of engineering survey and design to promote the green and low-carbon transformation and development in the field of engineering construction.Based on the concept of green low-carbon and combined with the local standards and policies of Guangxi,this paper discusses the working ideas of green low-carbon survey in the whole process of Guangxi through the three stages of pre-survey,survey and post-survey.
