摘要
以某深水港区地基工后短期沉降监测结果为基础,结合分层总和法及太沙基一维固结理论对土层固结系数进行了反演分析,并将反演得到的固结系数计算出的工后短期沉降与工后实测短期沉降进行了对比分析,分析结果表明反演得到的固结系数是可靠的。进一步将该固结系数代入太沙基一维固结方程,对工后可能发生的长期沉降进行了预测。与传统的长期沉降预测方法相比,由反演分析得到的固结系数进而对长期沉降进行预测的方法,更能反映实际土体的固结沉降机制,其结果也更加真实可靠。
Based on the in-situ monitoring data of the post-load settlement of a deep-water port, the consolidation coefficient of soils is back analyzed; and the post-load short term settlement is calculated. The result shows the great accuracy and good agreement with monitoring data. Long term post-load settlement is calculated and predicted with the proved consolidation coefficient of soils. By contrast with traditional methods predicting post-load settlement, this method is good at reflecting mechanism of consolidation of soils; and the result is much more reliable.
