This thesis is embedded in the general theory of quantum integrable models with boundaries, and the development of associated algebraic structures. We first consider the question of the diagonalization of the XXZ hamiltonian with nondiagonal boundaries. We succeed to find the two sets of eigenstates and eigenvalues of the model if the boundaries parameters satisfy two conditions. We introduce then a statistical physics model which we refer to be the face model with a reflecting end. Moreover, we compute exactly its partition function and show that it takes the form of a simple single matrix determinant. We show that these two problems are related through the vertex-face transformation and are solved using a common algebraic structure, the d...
