Comparing the residual strength of the grey-white expansive soil of ningming obtained by three different methods, the results are proved correct in the reference [ 2 ], and it's feasible to determine the residual strength of recompacted specimens 通過(guò)對(duì)比3種不同制樣方式得到寧明灰白色膨脹土的殘余強(qiáng)度,驗(yàn)證了文獻(xiàn)[2]中結(jié)論的正確性,進(jìn)一步探討了采用膨脹土重塑樣確定其殘余強(qiáng)度的可行性。
