摘要
Abstract
The analysis was made on the uneven settlement causes of a workshop foundation, it was considered the insuffi-cient bearing capacity of foundation, the consolidation of foundation soil and the influence of ground water are main rea-sons.The foundation reinforcement should be made by mainly grouting with combination of permeability and compaction fracture grouting.By the indoor experiments and engineering grouting tests on the grouting materials of SJP and pure cement slurries, it is proved that SJP slurries have the features of good initial fluidity, strong groutability and controllable initial and final setting time etc., which is superior to the traditional pure cements for the application in the foundation reinforcement of large porosity and heterogeneity.72 holes were grouted with SJP in the reinforcement project, 173m3 grouting materials and 173t cements were used, with about 108t cement being saved.关键词
