INFLUENCE OF BUILDINGS ON POTENTIAL LIQUEFACTION DAMAGE
Field case histories, model tests and simplified analyses suggest that conditions influencing liquefaction may be substantially different near a building than for the same soil profile in the free field. Field case histories are described to shed light on the problem of soil-structure interaction in liquefaction analyses. Shaking table model test results as well as centrifuge model tests indicate that the excess pore pressures and excess pore ratios below a structure may be significantly lower than in the free field away from the structure. Typical free-field liquefaction analysis procedure, and factors affecting the cyclic stress ratio causing liquefaction near a structure are discussed, as well as factors affecting the induced cyclic stress ratio near a structure. The combined influence of factors for various building types are reviewed. Case histories, model tests, and simplified analyses indicate that the beneficial influence of a structure may allow it to perform satisfactorily even though liquefaction develops to significant depth in the free field. Lower power pressures below a building do not, however, guarantee acceptable performance and bearing capacity, and settlement criteria must still be investigated.
