A REVIEW OF LIQUEFACTION OF DIFFERENT TYPES OF SOILS AND METHODS TO PREVENT FROM IT

In operation of several construction projects, including construction of buildings, bridges, roads, and dams, structures are built upon the soil. Generally speaking, soil plays an integral role in human activities and constitutes a ground for all civil projects. Consequently, proper identification of all types of soils as well as problems and features thereof would permit us to prevent disagreeable incidents. Soil liquefaction is one of such incidents, which frequently ensues from load of earthquakes. In recent decades, different earthquakes have occurred in different points of the globe. For instance, the 1990 Manjil-Rudbar (Iran) earthquake left several financial losses and casualties. Hence, identification of these types of soils would prevent events of this kind as much as possible. The present article makes attempts to address liquefaction causes, redress methods, and prevention ways. Possession of a proper understanding of this phenomenon and sufficient knowledge thereon would reduce probable harmful damages.
