SOILS, EARTHWORK & FOUNDATIONS chapt. 1

GEO - HAZARDS THAT ARE RELATED TO EARTHQUAKE PHENOMENA ARE

• FAULT SURFACE RUPTURE, SOIL LIQUEFACTION, SEISMIC SLOPE FAILURE

• Expansive soils

• Frost heave

Answer explanation

Section 1.4 GEO - HAZARDS

EARTHQUAKE PHENOMENA

Seismic shaking . Soil liquefaction . Seismic slope failure . Fault surface rupture

Non-earthquake phenomena include the following

• EXPANSIVE SOILS,

  SETTLEMENT,

  BEARING FAILURE

• ocean tide, soil liquefaction

The book is intended to be a guide & resource on soils & foundations for use by

• CONSTRUCTION PERSONNEL,

  CONSTRUCTION INSPECTORS

• architects

Geotechnical engineering refers to a discipline that involves

• 1.knowledge of applied geology

  2.soil formation & composition

  3.reaction of soils to loading

  4. 4.strength or stability of soils

• NA

Examples of use of geostructural engineering include

• design slab on grade foundation on expansive soils,

  design retaining wall, analysis of pavements

• NA

In a retaining wall the earth loading "at rest" are

• GREATER THAN THE EARTH LOADING IN AN "ACTIVE STATE"

• lower than the earth loading in an "active state"

Expansive soils can move footings in buildings

• EITHER UP OR DOWN AS A RESULT OF MOISTURE CHANGE IN CLAY SOILS

• only up

• only down

Expansive soils phenomena

• RARELY ENDANGER LIFE,

  RATE NEAR THE TOP OF ECONOMIC LOSS

• rate near the Bottom in economic loss

• are not geo hazards

Reference standard quoted in the code from organizations other than ICC may be found

• CHAPTER 35 OF THE 2015 IBC

• Chapter 1 of the 2015 IBC

A geo-hazard is a condition of the earth that could

• CAUSE A SAFETY CONCERN ,

  DAMAGE A STRUCTURE

• involve wind damage
