南充市储配站一号储气罐沉降监测数据处理与分析

Settlement Monitoring Data Processing and Analysis of No.1 Pressure Gas Storage Tank

随着国家经济的发展,居民生活水平提高及国家"煤改气"政策的推进,天然气作为一种清洁能源,将越来越多地应用到居民生活中。在天然气供应气源系统中,天然气储气罐是其中的重要组成部分,其安全问题备受关注。地基沉降作为一种常见的地质灾害,容易引起储气罐倾斜,严重的甚至会引起储气罐泄气、爆炸。因此,对天然气储气站进行沉降观测尤为重要。测量机器人是一种常用的沉降监测手段,具有精度高、成本低、易操作的优点。在测量中,受观测条件等因素影响,测量数据会不可避免叠加上"噪声"干扰,为剔除异常数据,在南充市储配站一号储气罐沉降观测中采用格拉布斯准则进行数据处理,并对测量数据进行了分析。

With the economic development in China and the promotion of the conversion of ＂coal to gas＂ policy, natural gas, as a clean energy, will be increasingly applied to the future life of residents. Natural gas storage tank is an important part of natural gas supply gas source system, and the tank safety has received much attention. As a common geological disaster, foundation settlement is likely to cause the gas tank to tilt, which may even cause gas storage tanks to deflate and explode. Therefore, it is particularly important to carry out settlement observations at natural gas storage stations. As a common means of settlement monitoring, seo-robot has the advantages of high precision, low cost and easy operation. In the measurement, due to the observation conditions and some other factors, the measurement data is inevitably superimposed on the ＂noise＂ interference, in order to eliminate the abnormal data, Grubbs criterion is used for data processing. Taking No. 1 gas storage tank of Nanchong gas storage and distribution station as an example, this paper introduces the observation technology and data analysis of the gas storage tank settlement.
