注浆法在处理既有建筑地基液化中的应用

Application of Jet Grouting in Dealing with the Liquefaction of the Soil and Foundation of Existing Buildings

汶川大地震给了我们深刻的启示,抗震设防不仅要重视新建建筑,同时要重视对既有建筑的抗震加固改造,如何有效消除既有建筑地基液化是其中的一个重要课题,目前对于建筑地基消除液化研究主要集中在新建建筑,文章主要探讨注浆法在处理既有建筑地基液化中的应用,并通过具体工程实践,分析地基液化机理,提出处理方法,通过试验、评价,取得了较好的效果。

Wenchuan Earthquake impressed us deeply： We should not only put our emphasis of the fortification against earthquakes on the newly built buildings but also on the exiting buildings and do something to reinforce it.It is an important project on how to remove the liquefaction of the existing buildings.Now,most research work focus on the newly built buildings.This essay mainly investigates the function of jet grouting in dealing with the liquefaction of the soil and foundation of existing buildings.It has proposed the way of dealing with it through experiments and it has got good effects by experiments and evaluation.
