摘　　要：从黄河下游放淤固堤工程的实际问题出发,文章分析了吹填土的沉降固结性能。指出砂性土比粘性土固结快,吹填砂性土比粘性土工程质量好,粘性土易产生裂缝,大堤背河不宜吹填粘性土。除此,文章给出了吹填土的沉降量计算方法。This paper has analyzed the characteristics of settlement and consolidation of soil warped by using a dredged-fill machine for strengthening the dykes along the lower Yellow River. The analysis shows that sandy soil not only consolidates faster, but also is better in engineering quality, comparing with clayey soil. Because the clayey soil is easy to crack, therefore, it is not suitable to strengthen dykes by this constructing method. In additim, the calculation method of settlement is given.
