文章通过灌砂法与核子射线法的对比,得出在湿密度、干密度和含水量的相关性计算结果,并在相关性检验评定中为显著。采用核子射线法检测石灰改良土的低密度是可行的。
Through the comparison of sand filling method and nuclear ray method, the article obtains the correlation results of wet density, dry density and water content, and is significant in the correlation test. It is feasible to use nuclear ray method to test the low density of lime modified soil.
