滨海液化地区大面积地基处理施工技术浅析

Analysis on Construction Technology of Large Area Foundation Treatment in Coastal Liquefaction Area

主要介绍了压密注浆挤密法,此方法具有小直径钻孔的特点,且点位布置灵活,浆液注入液化土层时,既能将液化土进行挤密,消除液化,同时当浆液凝固后,能够增加液化土地基承载力。对复杂地质的液化处理、提高地基承载力具有较好的效果。

This paper mainly introduces a kind of compaction grouting compaction method, this method has the characteristics of small diameter drilling, and flexible point layout, when the slurry is injected into the liquefaction soil, it can not only squeeze the liquefaction soil,eliminate liquefaction, at the same time, when the slurry solidifies, it can increase the bearing capacity of the liquefaction soil foundation. It has a good effect on the liquefaction treatment of complex geology and improving the bearing capacity of foundation.
