【摘要】 在高层建筑物施工过程中,随着楼层的增加和沉降变形增大,建筑物是否安全、其变形是否超标、以及未来发展趋势如何,需要随时掌握,以便采取相应的安全措施。以灰色系统理论为基础,针对建筑基础沉降的特点,建立相关的预测模型;在已有监测数据的统计分析基础上,求出预测参数,然后根据施工进度安排,可以对不同施工期间建筑沉降进行预测,以便确保施工安全。对北京某建筑工程进行了实例分析,通过6期监测结果的分析和后续变形的预测,经过工程实测对比和验证,其预测精度与实测相吻合,预测结果令人满意。更多还原

【Abstract】 During construction of tall buildings,safety or not and how obout development trend should be known as buildings story and subsidence value are increased,so that safe measures can be adopted.Predicting mould is established for character of foundation subsidence on the basis of gray theory.Predicting parameters are computed according to analysis of measuring data.Then in light of rate of progress,deformation is predicted in different periods of construction.Therefore safety is ensured.History-case analysis and prediction are carried through 6 measuring data.The result and precision are satisfied through engineering practice contrast.更多还原
