高真空击密法在曹妃甸港煤码头吹填土地基加固中的应用

摘要

During land reclamation by dredged fill, a soft ground containing soft clay layers is formed because of the hydraulic sorting and the method of high vacuum compaction is used for improving the soil. It is proved from the practice that the high vacuum compact method played a key role in ensuring quality of ground improvement, increasing the construction speed and shortening the construction period. Especially, it is very remarkably effective for improvement of soft ground sandwiched with soft clay, achieving better results than the single use of dynamic compaction.%对于吹砂造陆过程中,由于水力分选作用,形成软黏土夹层的平面区域,采用高真空击密法加固地基.实践证明,采用高真空击密法,对保证地基加固质量、提高地基处理速度、有效缩短工期起到了关键的作用,尤其对软黏土夹层地基加固效果十分显著,达到了单纯强夯法无法达到的效果.
