碩士 === 淡江大學 === 土木工程學系 === 88 === An optimization approach is presented in this paper for the design of reinforced concrete slurry wall. The design criteria are based on ACI Building Code (318-95) requirements, Building Regulations of ROC (1997) and Design Code of Practice for Foundations(1998). The design method of this thesis is based on the working stress design and ultimate strength design methods. The design variables include the thickness, embedded length, tension reinforcement, shear reinforcement, shrinkage reinforcement, splice length and development length. The minimum cost of construction of slurry wall based on the costs per unit volume of the concrete and the steel is taken as the objective function. The constraints include the requirements such as the thickness of wall, flexural strength, shear strength, ductility, the balance of active and passive earth pressure, heaving, boiling, splice length and development length of steel bars. The optimal approach utilized in this thesis is the GRG method of nonlinear programming. The results from this study may provide as a useful reference for the engineering design.
