Soil Dynamics And Special Design Aspects




1.1 INTRODUCTION

Section 1: SOIL DYNAMICS

1.1.1 Scope. This handbook is concerned with geotechnical

problems associated with dynamic loads, and with earthquake

related ground motion and soil response induced by earthquake

loads. The dynamic response of foundations and structures

depends on the magnitude, frequency, direction, and location of

the dynamic loads; the geometry of the soil-foundation contact

system; and the dynamic properties of the supporting soils and

structures. Dynamic ground motions considered in this chapter

are those generated from machine foundations and impact loading.

An example calculation of vertical, horizontal, and rocking

motions induced by machinery vibration is included. Soil

compaction resulting from dynamic impact and dynamic response

induced by impact loading on piles are also included. An example

calculation of dynamic compaction procedures for soils and an

example of pile driving analysis are included.

Elements in a seismic response analysis are: input

motions, site profile, static and dynamic soil properties,

constitutive models of soil response to loading, and methods of

analysis using computer programs. The contents include:

earthquake response spectra; site seismicity; soil response to

seismic motion, design earthquake, seismic loads on structures,

liquefaction potential, lateral spread from liquefaction, and

foundation base isolation.

Some special problems in geotechnical engineering

dealing with soil dynamics and earthquake aspects are discussed.

Its contents include: seismic design of anchored sheet pile

walls, stone columns and displacement piles; and dynamic slope

stability and deformations induced by earthquakes
