| Abstract: | Based on sewage engineering properties, the effect of potential geomorphic on optimal design for sewer system is discussed, and the potential geomorphic in optimal design is directly made use of. Space rightangle coordinate that reflects characteristic of potential geomorphic is considered as optimal design variable. Expense factor and expenses distribution coefficient with engineering meaning is definite, which carefully connect with characteristic of potential geomorphic. Computation formulation of expenses distribution coefficient is given. By means of equivalent linearlization of expenses factor, linear programming equations of sewer system is built. By comparison with other methods, this method can directly solve engineering problems than others. |
