Boundary-element technique research performed to solve soil-structure interaction problems is the basis for this report. Specifically, it was designed to answer questionable situations for long hydraulic U-Lock structures erected on elastic soil. A review of earlier research that employed the Kelvin-type element directed the decision in favor of Flamant-type boundary element. Both constant and linear elements were developed and many sample problems were dealt with to illustrate the capabilities of these elements in the problem situations of soil-structure relationships. The Flamant-type boundary element proved to be convenient, gave better results for displacement problems using the constant element, offered satisfactory behavior description of soil-structure response, required considerably fewer elements than the conventional model, provided more accuracy in stress analysis of structure, and was confirmed as very beneficial for use in input data preparation. Research was also conducted on soil-structure interaction problems with the structure modeled by the finite-element method and the soil modeled by the boundary-element method. A model problem suggested by the AEWES was selected for study and solving. The emphasis was to develop a convenient and economical technique to couple the boundary- and finite-element methods of analysis. A computer code for coupling the two methods has been developed in FORTRAN. Keywords: Soil mechanics; Structural engineering; Mathematical analysis.

Doria 6, 95125 Catania, Italy Soil-Structure Interaction is a challenging multidisciplinary subject which covers several areas of Civil Engineering. Virtually every construction is connected to the ground and the interaction between the artefact and the foundation medium may affect considerably both the superstructure and the foundation soil. The Soil-Structure Interaction problem has become an important feature of Structural Engineering with the advent of massive constructions on soft soils such as nuclear power plants, concrete and earth dams. Buildings, bridges, tunnels and underground structures may also require particular attention to be given to the problems of Soil-Structure Interaction. Dynamic Soil-Structure Interaction is prominent in Earthquake Engineering problems. The complexity of the problem, due also to its multidisciplinary nature and to the fact of having to consider bounded and unbounded media of different mechanical characteristics, requires a numerical treatment for any application of engineering significance. The Boundary Element Method appears to be well suited to solve problems of Soil- Structure Interaction through its ability to discretize only the boundaries of complex and often unbounded geometries. Non-linear problems which often arise in Soil-Structure Interaction may also be treated advantageously by a judicious mix of Boundary and Finite Element discretizations.

The first volume of this series dealt with the Basic Principles of Boundary Elements, while the second concentrated on time dependent problems and Volume three on the Computational Aspects of the method. This volume studies the applications of the method to a wide variety of geomechanics problems, most of which are ideally suited for boundary elements demonstrating the potentiality of the technique. Chapter 1 deals with the application of BEM to three dimensional elastody namics soil-structure interaction problems. It presents detailed formulations for rigid, massless foundations of arbitrary shape both in the frequency and time domains. The foundations are assumed to be resting on a linearly elastic, homogeneous, isotropic half-space and be subjected to externally applied loads on obliquely incident body. The chapter reviews the major advances in soil foundation interaction presents a series of numerical results and stresses the practical application of BEM, pointing out the high accuracy and efficiency of the technique, even when using coarse mesh discretizations.
