随着社会的不断进步,高层和超高层建筑物越来越多。为了保证建筑物正常使用的寿命和安全性,并为日后勘察设计施工提供可靠数据,沉降监测非常必要,而基准点稳定性分析是首要任务。详细阐述了分析基准点稳定性的方法:先进行秩亏自由网平差,再利用平均间隙法进行检验,并利用Matlab编程实现该方法,通过人机交互方式剔除不稳定点,并继续检验剔除动点,达到剔除所有不稳定点效果,从而大大减少建筑降监测基准点处理的内业工作量,并提高建筑降监测基准点的稳定性。通过算例验证了该稳定性分析方法及程序的可行性,适合在工程实践中推广应用。 With the continuous progress of society, high-rise and high-rise buildings more and more. In order to ensure the normal life and safety of buildings, and to provide reliable data for future survey design and construction, settlement monitoring is necessary, and the benchmark stability analysis is the primary task. The method of analyzing the stability of the reference point is described in detail: firstly, the rank gap is adjusted, and then the average gap method is used to test. The method is realized by Matlab programming. The method is used to eliminate the unstable point by means of human-computer interaction, and the test is eliminated Moving points to achieve the effect of eliminating all the unstable points, thus greatly reducing the construction work to reduce the base point of the work load, and improve the stability of the construction site to reduce the monitoring point. The feasibility of the stability analysis method and the program is verified by an example, which is suitable for application in engineering practice.
