Research on the Bearing Capacity of Compacted Mixed Soil Filling in Guilin City
The mixed soil in the area of Guilin has attracted the attention of many scholars due to its unique regional characteristics and complex engineering mechanical properties,while the engineering reference experience of compacted mixed soil as foundation filler is extremely lacking.Based on three engineering examples in Guilin City,the bearing capacity of three different foundations was calculated using shallow plate static load tests.The study has showed that,in the absence of measured ultimate bearing capacity,the Maxwell method and hyperbolic method can be used to extrapolate the ultimate bearing capacity by averaging multiple test points.The obtained ultimate bearing capacity is similar to the conventional method of selecting safety factors;comparing and analyzing the bearing capacity of three types of foundations,it is found that the mixed soil filling material has a significant compaction effect after rolling and a high bearing capacity.When used as a good soil filling material,it has certain engineering experience and economic effects.
