Abstract

If seismic hazards are deemed to be unacceptably high because of poor soil conditions, it is often possible to achieve improved seismic performance through the use of one or more soil improvement techniques. Poor performance is the result of inadequate strength, low stiffness, or insufficient drainage. Many improvement techniques have been evolved over the years, mostly through trial and error, aimed at improving at least one of these properties. When selecting one or more mitigation methods, it is important to consider the effectiveness of the improvement approach for the particular situation at hand, cost, environmental consequences, regulatory requirements, and technical feasibility. Also, careful assessment of the degree of ground improvement achieved is essential. The subject of soil improvement is quite extensive and a number of excellent sources and case studies are available in the literature. The aim of this paper is to highlight the most promising soil improvement techniques that are most commonly used for mitigation of seismic-hazard.

Soil Improvement Techniques for Mitigation of Seismic Hazards - An Overview

San Diego, California

If seismic hazards are deemed to be unacceptably high because of poor soil conditions, it is often possible to achieve improved seismic performance through the use of one or more soil improvement techniques. Poor performance is the result of inadequate strength, low stiffness, or insufficient drainage. Many improvement techniques have been evolved over the years, mostly through trial and error, aimed at improving at least one of these properties. When selecting one or more mitigation methods, it is important to consider the effectiveness of the improvement approach for the particular situation at hand, cost, environmental consequences, regulatory requirements, and technical feasibility. Also, careful assessment of the degree of ground improvement achieved is essential. The subject of soil improvement is quite extensive and a number of excellent sources and case studies are available in the literature. The aim of this paper is to highlight the most promising soil improvement techniques that are most commonly used for mitigation of seismic-hazard.
