摘要
为了提高土地利用率,缓解城市发展带来的压力,城市的建筑设计者逐步将建筑往高层发展,虽然满足了时代的需求,但存在安全隐患。高层建筑自身的荷载加上外界环境的影响,必然会发生不同程度的沉降,因此对建筑物的沉降监测就显得十分重要。介绍了建筑沉降监测理论和组合预测模型,并结合实例,探讨了监测方法,为建筑沉降预测提供了有效的保证。利用不同的预测模型对同一组数据进行沉降预测,再将实测结果与各模型预测结果进行对比。结果表明,灰色二次曲线函数组合模型的精确度最高。
In order to improve the land utilization rate and relieve the pressure brought by urban development,urban architects gradually develop their buildings to high-rise buildings.Although meet the times needs,but there are security risks.The load of high-rise buildings and the external environment influence will inevitably lead to different degrees of settlement,so it is very important to monitor the building settlement.In this article,we introduced the building settlement monitoring theory and combined prediction model,and discussed the monitoring methods based on examples,which could provide an effective guarantee for building settlement prediction.We used different prediction model to predict the same set of settlement data,and compared the measured results with the predicted results of each model.The result shows that the gray quadratic curve function combined model has the highest accuracy.
