https://doi.org/10.1007/978-3-8349-9724-1 (i.e. unlined tunnels), completely removes the initial stresses which existed in the area of tunnelling or excavations, Figure 10.1. Therefore, it may be reasonable to assume that the action of tunnelling and underground excavation can be modelled by the unloading of a cavity from the . stress state.

Better analysis and prediction methods for wellbore instability will definitely help reduce the costs associated with the wellbore breakout and instability problems.

Introductionand contraction of cylindrical or spherical cavities. Cavity expansion in soil or rock is a fundamental problem in theoretical geomechanics primarily because it provides a useful and simple tool for modelling many complex geotechnical problems.

Time-Dependent Solutionsve models based on visco-elasticity and visco-plasticity have been applied to tunnel problems. As far as soil mechanics is concerned, studies have been carried out on the pore pressure changes around a driven pile and an excavated tunnel in soils. This chapter will concentrate on the solutions with
