摘　　要：在地震设防烈度较高的孟加拉国河口三角洲地区的软土地基处理工程中,采用无骨料振冲技术和振动沉管桩技术相结合,成功消除新吹填粉砂土和砂土层的液化作用。检测结果表明:振动沉管桩和振冲桩技术,施工工艺成熟,质量可靠,能有效提高地基承载力和减小地基沉降。振动沉管桩和振冲桩技术,施工机具简单,造价低,非常适合经济欠发达的孟加拉河口三角洲地区地基处理工程。In this paper,in the soft soil foundation treatment project in the estuary delta area of Bangladesh with high seismic fortification intensity,the combination of the aggregate free vibroflot technology and the vibratory submerged pipe pile technology has been used to successfully eliminate the liquefaction of the silt and sand layer of the newly filled soil.The test results show that the vibration sinking pipe pile and vibroflotation pile have mature construction technology and reliable quality,and can effectively improve the bearing capacity of foundation and reduce the settlement of foundation.Vibrating tube sinking pile and vibroflotation pile technology,with simple construction tools and low cost,are very suitable for foundation treatment engineering in the underdeveloped delta area of Bengal estuary.
