Abstract

This paper is aimed to develop a new process for assessing degrees of liquefaction potential by the Dempster-Shafer theory of evidence (DS). By applying the DS combination rules, the proposed model combines different results of liquefaction potential by the simplified methods based on field data, including SPT-N, CPT-qc and Vs values. Beyond this, the entropy theory is used extensively in the study of criterion priority value for the potential degree models. To demonstrate this DS process, we take for examples of the Yuanlin area in Taiwan. Our results show that through the proposed model, the suitable liquefaction potential classification and uncertainty of any orientation can be obtained.
