沈阳建筑大学毕业论文毕业论文题目电子水准仪在建筑变形监测中的应用研究学院专业班级土木工程学院测绘08-01班学生姓名性别指导教师职称2012年6月15日摘要建筑变形监测是按照一定的周期对变形体进行重复观测以确定其形状在空间位置随时间的变化量,并利用观测结果总结出变形规律从而监测变形体的运动。如果变形超过了限差,就会影响建筑物的正常使用,严重的会使建筑物倾斜甚至倒塌。因此,在建筑物施工过程和运营期间,都需要对它们进行变形观测,确保工程建筑物的稳定性,为安全运行诊断提供必要的信息,以便及时发现问题并采取措施。本论文主要介绍了数字水准仪的结构、测量原理;数字水准仪的种类和特点,目前发展的现状,今后发展的趋势。以及数字水准仪在各种工程中的应用,尤其是在沉降监测中的应用;利用数字水准仪如何快速准确地获得监测对象的沉降信息,以便对监测对象进行及时的数据分析和准确的预报;依据电子水准仪的基本原理及其在建筑沉降监测中的应用进行研究和分析,从而得出对普及电子水准仪的应用和发展有益的结论。关键词:电子水准仪;变形监测;沉降观测AbstractBuildingdeformationmonitoringisrepeatedobservingthedeformationobjectswithacertainperiodtodeterminetheshapeofthespatialpositionwiththechangeoftime,andusingtheobservedresultstosumupthelawofdeformationandtomonitorthemovementofthedeformationobjects.Ifthedeformationexceedsthelimit,itwillaffectthenormaluseoftheIbuilding,andwillseriouslymakethebuildingtiltingorevencollapse.Therefore,intheperiodofbuildingconstructionandoperation,observingthebuildingdeformationtoensurebuilding’sstabilityisverynecessary.Andthenitcanprovidethenecessaryinformationforsafeoperation.Itcanalsofindproblemandtakemeasurestosolvetheproblemtimely.Thispaperintroducesthestructure,types,characteristicsandmeasurementprincipleofthedigitallevelinstrument.Thispaperalsoprobeintothedevelopmentsituationatpresentandthedevelopmenttrendinthefutureofthedigitallevelinstrument.Importantly,thispapermakearesearchoflargenumberofengineeringapplications,especiallyinthesettlementmonitoring,ofthedigitallevelinstruments.Usingthedigitallevelinstruments,itcanquicklyandaccuratelyobtainthemonitoringinformationofmonitoringobject,sothatthepredictionofmonitoringobjectcanbeobtainedtimelyaccurately.Toresearchandanalysisonthebasisprincipleofelectroniclevelanditsapplicationinbuildingsettlementmonitoring,theusefulconclusionsinpopularizationanddevelopmentofelectroniclevelinginstrumentapplicationisobtained.Keywords:Electroniclevel;Deformationmonitoring;SettlementobservatioII目录第一章电子水准仪的基本原理..............................................11.1引言...................................................................11.2电子水准仪的结构及测量原理.............................................11.3电子水准仪的种类和特点................................................21.3.1电子水准仪的种类....................................................21.3.2电子水准仪的特点....................................................81.4电子水准仪的发展现状及发展趋势........................................9第二章建筑变形观测.....................................................132.1建筑变形观测..........................................................132.1.1建筑变形观测概述...................................................132.1.2建筑变形观测的分类.................................................132.1.3建筑变形观测的特点.................................................142.1.4建筑变形观测的基本方法.............................................152.2变形观测的重要意义.......
