Abstract：
This paper takes two ｐrojects as examples, in which portland cement is used as the reinforcement material to make a consolidation over ground foundation by grouting.This has been proved that it has lower cost but better result. Example one is that Qunyi Art Museum used grouting to fill and consolidate its foundation. It has comｐared beｔween two original plans for foundation design(precast pile and gｒouting after filling and consolidation to estabｌish independent stylopodium), and the plan of foundation treatment has been chosen. In construction, it has been proved that grouting can improve bearing capacity of foundation soil and decrease differential settｌement. In example two, grouting through topdown construction method has been applied to the buiｌding of one dormitory apartment. Similarly, two plans(deep excavating and grouting to reinforce partial weak stratum for shallow-embedded foundation) were compared, and grouting was used to consolidate floury soil, remove liquefaction and dｉffｅrential settlement of foundation.
