Geotechnical Reconnaissance of the Effects of the January 17, 1995, Hyogoken-Nanbu Earthquake, Japan

摘要

The purpose of the report is to provide an overview of the principal geotechnicalaspects of the earthquake. The seismological aspects of the Kobe earthquake are presented in Chapter 2. The regional seismicity and tectonics, including local geology, are reviewed first, followed by a discussion of the source characteristics of the earthquake. Liquefaction and liquefaction related effects are described in Chapter 3. The extent of liquefaction provides a unique opportunity to assess the performance of various types of foundations under conditions of loss of bearing capacity and lateral support, and subjected to lateral spreading. The performance of improved ground is reviewed in Chapter 4. The observation of the behavior of dams and levees are presented in Chapter 5. The damage to lifeline systems is described in Chapter 6, and other geotechnical aspects of the earthquake damage, including the performance of slopes, structural fills, mechanically stabilized slopes, and landfills, are presented in Chapter 7.
