FEQDrain: A Finite Element Computer Program for the Analysis of the Earthquake Generation and Dissipation of Pore Water Pressure in Layered Sand Deposits with Vertical Drains
One method of soil stabilization for potentially liquefiable sites is the use of a system of vertical drains to dissipate the excess pore water pressure generated by earthquake loading, thus avoiding liquefaction. Performance assessments for these systems require the estimation of vertical drain spacing such that a maximum threshold level of excess pore pressure ratio is not exceeded. This report discusses the development of a computer code to analyze three dimensional pore pressure generation and dissipation in layered sand deposits with vertical drains. The analysis includes modeling of gravel drains and prefabricated drains with storage capacity. This report describes the selection of input parameters and illustrates the application of the program for various types of drains.
