Thisbook is directed at the heart of Engineering Geology, where geology is used to identify potential problems arising from ground conditions; it describes how to investigate those conditions and to define an engineering response that will either avoid or reduce or even eliminate the problems revealed.It has written for students of geology, engineering geology and civil engineering and illustrates how geology is related to calculations of stability, deformation and groundwater flow. The reader is constantly presented with the "big geological picture" that is so often lacking, when only site details are available, and yet so necessarywhen an adequate engineering solutionis tobe found.
