摘要

海堤工后沉降分析预测对工程维护和灾害防治具有重要意义。以海堤工后初期监测资料为基础，运用分层总和法和太沙基一维固结理论反演了土层固结系数，并通过对固结系数变化规律的分析，提出采用改进变维分形预测模型对具有较强趋势性的固结系数进行预测，进而对海堤工后可能发生的长期沉降进行预测。以浙江省洞头县北岙后二期东围堤工程的海堤监测数据作为研究对象进行了验证计算，结果表明，该方法反映了实际土体的固结沉降机制，能够较好地预测海堤工后沉降趋势，具有一定的工程实用意义。

Abstract

The analysis and prediction of seawall foundation's post construction settlements are very meaningful for engineering maintenance and disaster prevention. Based on seawall's early post-monitoring data in the initial stage of construction

the soil consolidation coefficient is inversed by using layer-wise summation method and Terzaghi's consolidation theory; and an analysis is also carried out the variation laws of consolidation coefficient. In this way

the authors adopt the improved variable dimension fractal prediction models to forecast the consolidation coefficient with strong trends; and then predict the contingent long-term post construction settlement of seawall. As a test

the prediction model is applied to the seawall monitoring data of Beidaihou second east-causeway project (located in Dongtou County of Zhejiang Province). As a result

it reflects well the mechanism of soil body’s consolidation and settlement

and predicts better the trend of seawall’s post construction settlement.
