Study Of Optimization Design Of Retaining Wall Reclining On The Slight Slope Built On Soft Foundation In Water Conservancy

Retaining wall is a construction form of the widespread adoption in engineering field , although appeared the new form of the wall in recent years with the new way of doing, the gravity wall built with stone is still the main form, and therefore the study on optimization design of the gravity wall built with stone has very important meaning.The retaining wall reclining on the slight slope built on soft foundation is usually used in protecting the shore of river, the contradiction between the lack of impartiality in stress of the base and the small stress allowed by the foundation as well as the lack of stabilization of the breast wall is a hard nut to crack in the engineering .In the paper, a tenon-base is added under the base of the retaining wall, on the study of the choice of the parameters and formulas used in calculation and the research of theory used in calculation, method used to deal with the load, etc, the writer gives a way to crack the nut mentioned above paragraphs and presents a qualitative and quantitative analysis about them, such as the equivalent inner friction-angle ( ψD) and the passive press of the clay (Ep), etc. In the end of the paper, using modern optimization method, a design of the retaining wall reclining on the slight slope built on soft foundation is done, the result is economical, and accords with the fact.
