对贵城道路设施公司厂房地基不均匀沉降成因分析，认为地基承载力不足、地基土固结和地下水影响是主要原因，应采用以充填为主，渗透、压密劈裂联合作用的注浆加固方式进行地基加固。通过SJP注浆材料和纯水泥浆2种浆材的室内实验和工程注浆试验，证明SJP浆材具有初配流动性好、可灌性强、初凝与终凝时间可控等良好特性，用于大孔隙性、不均质地基的加固优于传统纯水泥浆，解决了普通水泥浆漏失量大、加固效果差或无法加固的问题。该加固工程采用SJP浆材注浆72个孔，消耗浆材173 m3，消耗水泥173 t，节约水泥约108 t，取得了很好的经济效益。

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.
