As anationally planned textbook for regular higher education during the “11thFive-Year Plan” period, this book has systematically elaborated the designprinciple, calculation theory and method and construction technique of allkinds of normally used subgrades and foundations from road, bridge and otherartificial constructions. This seven-chapters-composed book has explainedshallow foundation, pile foundation, and the open caisson foundation on naturalsubsoil, underground continuous wall and foundation treatment, as well asfoundation works of several special areas. The book is attached with examplesof rigid spread foundation, pile foundation and the open caisson foundation.

Thisbook is a teaching material for the civil engineering major of higher college(road, bridge, highway tunnel and geotechnical engineering oriented) as well asRoad Bridge and River Crossing major. Besides, it can also be used as areference for the pupils and staff of relevant majors and for technical laborswho work on foundation engineering design and construction.
