基于Matlab的建筑沉降监测基准点稳定性分析

Stability Analysis of Building Subsidence Monitoring Datum Points Based on Matlab

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 constant progress of the society,there are more and more tall and super-tall buildings.In order to guarantee life of the normal service,safety buildings and provide reliable date for the following construction survey,stability analysis of building is very necessary,and analysis of datum points is the primary task.The method of analyzing the stability of datum point is described in detail.First,rank defect free network adjustment,and then use mean spacing method to test,at the same time,using Matlab programming to achieve the method.This method is convenient to eliminate the unstable points,continue to check out the fixed point,eliminate all unstable points by the way of human-computer interaction.This method greatly reduces the workload and improves stability of building subsidence monitoring datum points.The feasibility of the method and the program is verified by an example,and is suitable for popularization and application in engineering practice.
