This study, using soil that were collected by excavating pits to a depth of -20 m in Āgōng diàn shuǐkù Reservoir ( 阿公店水庫 ) and Báihé shuǐkù Reservoir (白河水庫) as examples to investigating the characteristics of soil behavior caused by a cyclic loading. The purpose of this study is to understand the liquefaction resistance properties of the soil to determine whether it is soil that may liquefy. The remolded specimens were then subjected to a homogeneity test to verify the feasibility of using the remolding technique to simulate sliding surface materials. Thereafter, an uniaxial and triaxial test was conducted into two air-dried and saturated pecimens, to establish the strength failure criterion. Experimental results indicated that the soil have potential to liquify, which could be used to infer the relationship between the behaviors of the CSR value and the number of cycle to get failure of the soil, and to further establish for field applications, including seismic slope stability analyses liquefaction potential of unsaturated soils located in natural, horizontal soil deposits. For instance, a geotechnical engineer can assess the cyclic resistance of unsaturated tailings for both the wetting and drying path embankment.
