摘要
该文结合某电厂堆载预压地基处理施工监测实例,对获取的大量监测数据进行了分析.通过对数据进行多项式拟合,采用三点法计算最终沉降量以及固结度;同时采用经验双曲线法计算软基处理的最终沉降量与固结度,并对两种方法进行分析.结果表明,经验双曲线法计算的固结度比三点法更小,指出了两种方法在实际工程中应用的注意事项,并做出了合理选择.
Abstract
This paper analyzes a large amount of monitoring data obtained by combining a construction monitoring example of a certain power plant's preloading foundation treatment.By fitting polynomial to the data,the final settlement and consolidation degree are calculated by using the three-point method.At the same time,the empirical hyperbolic method is used to calculate the final settlement and consolidation de-gree of soft foundation treatment,and the two methods are analyzed.The results show that the consolida-tion degree calculated by the empirical hyperbolic method is smaller than that by the three-point method.Points out the precautions for the application of two methods in practical engineering and makes reasona-ble choices.
