Excerpt from Foundations of Bridges and BuildingsA large proportion of space is devoted to piles and pile driving, since young engineers are more likely to obtain their early experience with pile foundations than With any other class of foundation construction. Many facts derived from experience are given to emphasize and illustrate the application of funda mental principles and to form a rational basis for that kind of j udgment Which is such an important element in an engineer's professional practice. The undesirable features of considerable pile driving in this country have been due as much to the as sumption that the art of pile driving is so simple that the aid of science is not essential, as to the attempt of some engineers to base the art upon theoretical rules Which fail to take into account many practical factors of the problem. Another reason for extending the treatment is due to the recent intro duction of concrete piles Which Will help to retain the dominant place that pile foundations have held heretofore among other classes of foundations.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
