A PRACTICAL APPROACH FOR SETTLEMENT OF BUILDING SUPORTED BY PILED-RAFT(Structures)

Abstract

This paper presents a new practical approach (named "CEM") for quickly and easily calculating the settlement of piled rafts in layered soft soils. We introduce the new concept "the equivalent column" for pile and surrounding soils in the method. Calculating the settlement of piled raft using the CEM provides a close approximation to results observed from the 5-story and the 3-story buildings in Tokyo area, as well as obtained from parametric studies bv the three-dimensional finite element method.
