摘要
目前,我国沿海地区因经济发展,需要进行大面积填海造地以用于项目建设。填海造地就面临着软土地基加固的问题,特别是软弱地基具有含水率高、压缩性大、强度及承载力低等特点,而真空联合堆载预压地基可以以较低成本进行大面积的地基处理,较短时间内就可减小地基含水率,提高地基承载力,因此,目前国内大型软弱地基基本上采用真空预压地基处理技术。
At present, the coastal areas of our country need sea reclamation for project construction because of economic development. Sea reclamation is facing the problem of sott soil foundation reinforcement, especially the weak foundation has the characteristics of high water content, high compressibility, low strength and low bearing capacity, and vacuum preloaded foundation can be used for large area foundation treatment at lower cost, and reduce the water content of foundation and improve the bearing capacity of soil in a short time. Therefore, the vacuum preloading foundation treatment technology is basically adopted in the treatment of large scale soft ground in China.
