This paper sets out a simplified approach by which the practical foundation designer can undertake the relevant calculations to satisfy the requirements for deep foundation design in seismic areas. The following matters are dealt with:
a. Design issues that should be addressed;
b. Pile design for axial loading, including the possible effects of liquefaction;
c. Pile design for lateral loading where liquefaction does not occur;
d. Pile design for lateral loading where liquefaction does occur;
e. Measures to mitigate against liquefaction effects.
The paper is a modified version of a paper presented in 2013 to the 19th NZGS Geotechnical Symposium, Queenstown, New Zealand.
