Abstract

Tunnels have become an inevitable part of the urban transport systems, having greater demands now-a-days. Along with advantages of tunnel, it comes with deleterious effects on the structures adjacent to its alignment, which may be due to vibrations / volume loss of the soil material. Tunnelling may pose serious problems to the buildings which are historically important, vulnerable, old etc. There are
various measures to mitigate the effect of tunnelling on the adjoining structure. Providing series of micropiles along the tunnel alignment is one such measures. In this study, analyses of micropiles are carried out using MIDAS GTS 3D software. The various parameters considered for analyses are length, number & spacing of micropiles, type of soil and foundation. Reduction in settlement of raft & pile foundations due to provision of micropiles were evaluated and optimum number, length & spacing of micropiles were decided from the analysis.
