尾矿生态脆弱区场地测试技术与土工参数评价方法研究进展
A review of site testing technology and geotechnical parameter evaluation method in tailings ecological fragile area
摘要
Abstract
Piled tailings usually have high water content,great compressibility as well as high potential en-ergy,and are also prone to flow and liquefaction.Piled tailings are a potential disaster source and environmen-tal pollution source in tailings ecological fragile areas.Therefore,the characterization and evaluation methods of geotechnical parameters on the site of tailings ecological fragile area are particularly important.This paper reviews and summarizes the latest research progress regarding the site testing technologies in tailings ecological fragile areas in China and abroad.The representative research results and evaluation methods for geotechnical engineering characteristics involving physics,mechanics,drainage,state,yield strength,liquefaction and re-sidual liquefaction resistance,are also summarized.The analysis shows that,the in-situ testing can more accu-rately collect the geotechnical parameters of the site in the ecologically fragile area of tailings in comparison with the laboratory tests,and thus the in-situ testing technology is more widely adopted method in the practical engineering.In the in-situ testing technologies,the modern piezocone penetration test(CPTU)technology can reflect the continuous geotechnical parameters,and it shows unique advantages and great potential of engi-neering application in the performance evaluation of tailings.In the future,it is worth strengthening the re-search on the modern in-situ testing-based evaluation method for vulnerable area of tailings pond,which may benefit to ensure the successful construction and safe operation of the engineering projects in the tailings eco-logical fragile areas under the strategy of a country with strong transportation network.Meanwhile,the in-situ testing technology with great adaptability to extreme environment is a key development direction of geotechni-cal testing in the tailings ecological fragile areas in the future.关键词
