摘要 提出了一种分级加载条件下提早预测地基沉降的新方法——沉降差法。该方法将各级荷载作用下的地基沉降发展规律统一了起来,能同时利用各级荷载下的实测数据来进行线性拟合和预测,可在工程填土施工过程中提早预测在设计总荷载作用下的地基总沉降量,以指导工程施工。 A new method named settlement differential method was proposed. By use of the method the settlement of ground could be predicted in advance under the condition that fill material was added onto the ground by layer. The development of ground settlement at different filling stages was revealed, so the ground settlement data observed at different filling stages could be used in linear fitting to predict the ultimate ground settlement. It was useful in fill construction that the ultimate settlement of ground could be precisely predicted in the course of filling.
