In this paper, a testing method which analyzes effect of alkalinity of hardened cement pastes on soil's is put forward, and layer soil sampler is designed.

24 soil sampler were employed for the study, and the correlation coefficients in 21 soils were statistically significant at 1% level, and the other were at 5% level.

在24个供试土壤中，有21个土壤的相关系数达到极显著水准，3个达显著水准。
