摘要
在高层建筑物施工过程中,随着荷载的增加,沉降值增大,建筑物是否安全以及未来发展趋势如何,需要随时掌握他们之间的动态关系,以便采取合理施工顺序和相应的安全措施.以灰色系统理论为基础,建立相关的预测模型;在已有监测数据的基础上,求出预测参数,然后根据施工进度与荷载变化,可以预测不同施工期间建筑沉降值,以便确保施工安全.本文对某建筑工程进行实例分析,建立动态预测模型,并对后续变形进行预测,实测对比验证表明,其预测结果和预测精度令人满意.
During construction buildings, subsidence increases as load increase, and safe or not and development trend are need to be known, so that construction sequence and safe measures are adopted. Predicting mould is established on the basis of gray theory. Predicting parameter is computed according to analysis of measuring data. Then in light of construction rate and load change, subsidence value is predicted in different times of construction. Therefore safety is ensured. The prediction result and precision are satisfied through History -case analysis and contrast.
