基于高层建筑物施工过程可近似地看为一个线性加载的过程和S形曲线的特征,将广泛用于经济和资源预测的S形曲线模型应用于高层建筑物沉降预测,建立了高层建筑物的广义S形曲线时间-沉降预测模型,阐述了广义S形曲线模型参数的计算方法,并结合两个工程实例与常用的指数曲线法和双曲线法进行了对比计算分析,结果表明广义S形曲线模型用于沉降预测的效果较好,可供工程应用参考。
Based on the high-rise building construction process can be seen as a linear load process and S-curve characteristics, will be widely used in economic and resource forecasting S-curve model applied to high-rise building settlement prediction, the establishment of high-rise buildings The generalized S-curve time-settlement prediction model is described. The calculation method of the generalized S-curve model parameters is expounded. By comparing the two engineering examples with the commonly used exponential curve method and hyperbola method, the results show that the generalized S-curve The model is better for settlement prediction and can be used as reference for engineering application.
