室内固结试验测定基准基床系数的方法与分析

Method and Analysis of Consolidated Test in Room for Determining Reference Coefficients of Subgrade Reaction

通过对室内固结试验相关参数的设定,模拟地基土承载变形试验,根据固结试验的压力-变形关系,计算地基土的基床系数,并通过相应的换算求取土的基准基床系数。从而实现基准基床系数的批量测定,解决现场试验条件和经费的限制的问题,提供更多的试验数据,为工程设计使用。

Through the way to set parameters of the consolidated test in room,the analogue test of bearing settlement of foundation soil was carried.Coefficients of subgrade reaction were worked out according to the relation of pressure and settlement.Reference coefficients of subgrade reaction of foundation soils were calculated out by converting.Thus it realized in room to test reference coefficients of subgrade reaction in batches and solved restriction of the field condition and the expenses of field test.It can provide more datum for engineering design.
