Compilation of Design Guideline for Piled Raft Foundation

Piled raft foundation is being used widely nowadays, due to its advantages in
foundation construction. Piled raft can be used for different cases, such as settlement
reducers, and improving bearing capacity of shallow foundation. Piled raft foundation is
one of the complex foundation, because it has to consider varies of aspects and
consideration. In UTP, especially for civil engineering students, this guideline will help
them to learn about piled raft foundation. In this project, one design guidelines will be
compiled to help students and others user, in learning the piled raft design. The design
guideline will focus on the used of piled raft as settlement reducer for development on
soft soil area, where friction pile is used in the design and it will be a "floating" piled
raft. In others words, the pile group are not driven until reached the hard layer, but its
length will cut at certain depth. Simple calculation methods introduced by various
researchers are used in the design calculation, such as Randolph, Poulos and etc. The
guideline coverage is ranging from the early staged of soil investigation until design
analysis. All the information are collected from the available guideline produced by
other parties such as geotechnical consultant, reference books, journals and articles. At
the end of this project, one compilation of piled raft design will be documented and
together with a spreadsheet, with the objective to assist students in design calculation.
