| 摘 要： | 根据大面积深厚吹填砂工程的特点，分析太沙基一维固结理论在分层地基，分级加载等复杂工程条件下应用的可行性，提出了相应的简化计算模型，并编制一维固结计算程序。结合上海某围海成陆港区堆场工程，对其吹填砂层及软弱下卧层的固结沉降进行了计算分析，通过计算结果和离心机模型试验结果的对比分析，对计算模型进行修正，提出了大面积吹填砂工程地基沉降预估方法。

| Abstract: | The feasibility of Terzaghi’s one-dimensional consolidation theory applied to complex engineering condition of layered soil foundation and multi-stage loading is analyzed based on the characters of the great area super-hill filled sand foundation engineering. The simplified calculation model and the corresponding one-dimensional consolidation program are given to calculate soil settlement. Combined with the reclamation port construction project in Shanghai, the consolidation settlements of filled sand and soft substratum are calculated and analyzed in details by the program. Through comparison between the results of calculation and centrifuge model test, the simplified calculation model is modified; and the method for predicting and estimating the soil settlement of deep filled sand and substratum is put forward. |
