建筑资讯建筑技术开发·12·BuildingInformationBuildingTechnologyDevelopment第50卷第2期2023年2月基于激光扫描的露天矿山边坡监测与稳定性分析钟金荣(福建省核工业二九五大队,福建龙岩364000)[摘要]以某矿山边坡为研究对象,采用激光扫描技术,对其坐标进行监测,并根据监测结果分析其稳定性,采用多站点平差法对其监测结果进行优化,并将其结果与近景摄影测量技术得出的检测结果对比,以验证激光扫描技术结果的准确性,得出以下结论:激光扫描仪得出的矿山边坡误差范围内点云数主要集中于–0.2500~0.2500m,其中,第2期的误差范围内点云数最大,其值为198724个,此精度范围内的误差仅为0.5m,采用激光扫描仪对矿山边坡进行监测的准确性较高。不同误差区域误差范围内点云数总体呈正态分布,说明该矿山边坡的较为稳定,发生滑坡的概率较小。[关键词]矿山边坡;激光扫描;多站点平差[中图分类号]TD176[文献标志码]B[文章编号]1001-523X(2023)02-0012-03SURFACEMINESLOPEMONITORINGANDSTABILITYANALYSISBASEDONLASERSCANNINGZhongJin-rong[Abstract]Inthisstudy,amineslopeistakenastheresearchobject,anditscoordinateismonitoredbyusinglaserscanningtechnology,anditsstabilityisanalyzedaccordingtothemonitoringresults,andthemonitoringresultsareoptimizedbyusingmulti-stationadjustmentmethod,andtheresultsarecomparedwiththedetectionresultsobtainedbyclose-rangephotogrammetrytoverifytheaccuracyoftheresultsoflaserscanningtechnology,theconclusionisasfollows:thenumberofpointcloudsintheerrorrangeofthemineslopeobtainedbythelaserscannermainlyconcentratesin–0.2500~0.2500m,amongwhich,thenumberofpointcloudsintheerrorrangeofthesecondstageisthelargest,anditsvalueis198724,theerrorinthisaccuracyrangeisonly0.5m,andtheaccuracyofmonitoringthemineslopebylaserscannerishigh.Thepointcloudnumberindifferenterrorregionsisgenerallynormaldistribution,whichindicatesthattheslopeofthemineisrelativelystableandtheprobabilityoflandslideissmall.[Keywords]mineslope;laserscanning;multi-siteadjustment矿山边坡易发生滑坡等地质灾害,对其进行监测和测量可对即将发生的自然灾害做出预警,提高矿山边坡稳定性。闫魏力等[1]采用三维激光扫描技术,对某矿山进行测量,结果表明,该方法的准确性...
