The SELECTION OF THE TREATMENT METHOD OF COLLAPSIBLE LOESS FOUNDATION SHOULD be based ON the type OF BUILDING, THE type OF SITE, the thickness OF COLLAPsible loess, the distribution OF COLLAPsible coefficient along the depth, the source of materials and the construction conditions, and through technical and economic analysis, so as to take measures according to local conditions and protect the environment. The common treatment methods of collapsible loess foundation can be selected according to the table.
Treatment method of collapsible loess foundation
Foundation treatmentBefore construction, test or experimental construction should be carried out on representative sites for the selected foundation treatment methods, and the design parameters and treatment effects should be checked through necessary tests. If the design requirements cannot be met, the reasons should be identified and measures should be taken or the design should be modified.
In the rainy season, winter choose soil (or ash soil) cushion method, compaction method or soil (or ash soil) compaction pile method to treat the foundation, during the construction should be taken to prevent rain, anti-freezing measures, protect the soil material from rain wet or frozen, and should prevent the surface water flow has been treated and untreated foundation pit or foundation groove.
