Testing Method and Values of Coefficient of Subgrade Reaction
【摘要】 本文提出了一种在考虑p~s曲线非线性特征条件下将不同尺寸载荷板的试验结果化为标准的基床系数的方法 ,讨论了载荷试验下沉量取值对换算结果的影响 ,建立了不同土类室内压缩模量与基床系数之间的数值关系 ,最后 ,验证了本文方法在数据上的合理性。本文方法将大大地方便对已有成果资料的有效利用
【Abstract】 The method for the conversion of any PLT results into the coefficient of subgrade reaction is put forward, which is able to take the non-linear characteristics of the p-s curves into account. The affection of settlement value chosen in the calculation of the coefficient is discussed and the relationship between the modulus obtained in laboratory tests and the coefficient is established. The said method can facilitate making good use of the data accumulated in the past.
