Abstract

A study of interactive ground behaviour due to tunnelling adjacent to existing piles has not been recognized well for the most geotechnical engineers so far. Because this is a very sophisticated boundary condition problem. In this study, therefore, the author has conducted both the laboratory model test and finite element analysis (FEA) to figure out such a complicated ground behaviour related to shear strain formations. Based on the model testing and FEA results, a boundary line which divides into two distinctive shear strain formations in relation to the locations of end-bearing pile tips was proposed. The author believes that the proposed boundary line may be helpful for planning the appropriate tunnel positions for avoiding damage of buildings which supported by piled-foundations in urban areas.
