Laboratory test is conducted to study the evolution law of the fissures of Nanyang expansiveclay under wetting and drying cycles.
对南阳膨胀土在反复干湿循环作用下的裂隙演化规律进行了室内试验。

The contribution of suction to shear strength for the compacted expansiveclay was more significant than that for a compacted kaolin.
吸力对该膨胀土抗剪强度的贡献高于压实高岭土。

Because soft rocks have low strength and high porosity and contain large amount of expansiveclay minerals, the freezing-thawing process of soft rock is complicated.
