高层建筑物沉降观测与预测

对北京工业职业技术学院综合楼沉降观测点和水准基点测量精度进行了方案设计与合理性研究。利用观测的原始资料,采用灰色GM(1,1)模型对封顶前、封顶后进行预测,并和精密水准测量的结果进行了对比,预测结果与实际结果吻合较好,所建预测模型精度高,在实际工程中有一定应用价值。并给出了完整的沉降观测的最终成果。

On the Observation and Prediction of the Settlement of High-Rise Buildings

This paper provides a design of settlement observation point for the main building in Beijing Polytechnic College and makes a study on the rationality of the benchmark measurement accuracy of the main building.Making use of the original data of the observation and by means of gray GM(1,1) model to make prediction before and after the sealing of the building,then to make contrast with the result of the precise measurement,it finds out that the prediction meets well with the actual result and thus makes the conclusion that the model built for prediction is of high accuracy and to some extent of high value in the actual engineering.The paper provides also with a complete settlement observation result of the building.
