Seepage into a Sheeted Excavation* Available to Purchase

A number of problems of steady two-dimensional seepage flow around sheeted excavations in porous media have been investigated at the Building Research Station in recent years. This paper presents a general survey of the work carried out and summarizes the more important results which have been achieved. The assumptions of the theory of seepage flow are reviewed briefly and the difficulty of interpreting the practical value of theoretical results is discussed. Some relaxation solutions for one type of problem are given and graphs have been prepared in order to facilitate the application of equilibrium criteria.

The application of the theory in the safe design of sheeted excavations is considered and some practical suggestions are offered.
