高精度电子水准仪在煤仓沉降观测中的应用

APPLICATION OF HIGH-ACCURACY ELECTRONIC LEVEL TO SUBSIDENCE OBSERVATION OF THE COAL BUNKER

随着社会的发展,高层建筑物及高耸构筑物越来越多,其安全问题越来越受到社会各界的关注,为了保证建(构)筑物的安全性使其顺利施工和施工后的安全运营及其正常使用寿命,建(构)筑物沉降观测的必要性和重要性愈加明显。进行沉降观测所使用的仪器目前主要是水准仪,由于测绘技术的发展,电子水准仪的出现为水准测量开辟了新天地,本文以电子水准仪在煤仓沉降观测中的应用实例,首先简述了对煤仓进行沉降观测的意义,接着介绍了DL101C电子水准仪的功能及技术特点,阐述某煤矿主井煤仓沉降观测基准点和沉降点的布设和观测方案、沉降观测的数据处理与成果管理,并对煤仓沉降进行了简单的分析。最后简要总结了电子水准仪在实测中的优点及应注意的问题。

With the development of the society, there are more and more high-story buildings and towering structures erecting, so safety becomes one of the most important things to be considered. For the purpose of building structures smoothly, operating them safely and prolonging their normal service life after construction, the subsidence observations to the construction become much more important. At present, electronic level is used to make subsidence observations. Giving the application example of electronic level in subsidence observation of the coal bunker, this paper first briefly explains the meaning about deformation of the coal bunker, and then introduces the main functions and technological characteristics about KL101C electronic level. Furthermore, the distribution of data points and subsidence points, the oservation scheme, data processing of subsidence observation, result mamagement and the analysis of coal bunker subsidence are explicated. Finally, the advantages of the electronic level in surveying are summarized and some problems should be paid attention to.
