      This paper outlines the mitigation measures performed to address the liquefaction concerns of the foundation ground underneath a manufacturing plant site in Nagoya, Japan. Initially, a detailed soil investigation was performed and the liquefaction Author: Rolando P. Orense, Yukio Morita, Masanori Ide. To safely resist large earthquake events, it is recommended to have the following safety measures for the design of the dam: (1) free board should be increase at least to m instead of the m of the final design; (2) the foundation of the dam should be stabilized against liquefaction hazard; and (3) the embankment Cited by: 2.

Into the ODOT Liquefaction Mitigation Policy. This study has demonstrated the utility, and limitations, of soil improvement solely by densification techniques. In some cases soil densification techniques for mitigating seismic hazards.

In Oregon, the evaluation of soil liquefaction and abutment performance are complicated by the rather unique seismo-tectonic setting and the prevalence of silty soils.

Current design methods for evaluating permanent, seismically-induced deformations of earth structures are based on rigid body, limit equilibrium and “sliding-block ” procedures that are poorly suited for modeling soil liquefaction and establishing the pattern of embankment-abutment-foundation deformations.

In Oregon, the evaluation of soil liquefaction and abutment performance are complicated by the rather unique seismo-tectonic setting and the prevalence of silty soils along the primary. This is the appendix to the report entitled, "Assessment and Mitigation of Liquefaction Hazards to Bridge Approach Embankments in Oregon".

The objective of this study is to provide a simple methodology to conduct preliminary seismic assessment and ranking of bridge embankments in order to identify and prioritize embankments. As described above, the assessment of liquefaction risk is the focus of this chapter, in terms of likelihood and its impact.

The framework presented in Fig. shows the key steps involved in assessing liquefaction risk, which are discussed in further detail in the following sections. To fully define the risk, detailed assessments of liquefaction Cited by: 2.
