Abstract

A brief evaluation is made of research conducted to determine liquefaction potential for the sandy soils along the coastal areas of Peru, which present such characteristics that make them susceptible for development of this particular phenomenon under a very intense earthquake. It has been determined for the specific case of the Chimbote area, that some parts of the city present dangerous unstable conditions due to the present position of the water-table level, soil type and their relative density, that caused liquefaction during the 1970 earthquake. On the other hand, in these areas the simplified method has been employed to establish the soil liquefaction potential with the help of plentiful field tests and information, comparing these evaluated results with other most sophisticated methods based on the propagation of shear waves employing the continuous solution of the wave equation, taking into account the longitudinal and transversal components of the 1970 Peru earthquake and three different base accelerations. Also, the prediction conducted, which recommends the lowering of the water-table to convenient depths, shows that the danger of liquefaction diminished in the investigated area.

Comparative Studies of Soil Liquefaction Potential During the 1970 Peru Earthquake

St. Louis, Missouri

A brief evaluation is made of research conducted to determine liquefaction potential for the sandy soils along the coastal areas of Peru, which present such characteristics that make them susceptible for development of this particular phenomenon under a very intense earthquake. It has been determined for the specific case of the Chimbote area, that some parts of the city present dangerous unstable conditions due to the present position of the water-table level, soil type and their relative density, that caused liquefaction during the 1970 earthquake. On the other hand, in these areas the simplified method has been employed to establish the soil liquefaction potential with the help of plentiful field tests and information, comparing these evaluated results with other most sophisticated methods based on the propagation of shear waves employing the continuous solution of the wave equation, taking into account the longitudinal and transversal components of the 1970 Peru earthquake and three different base accelerations.
