【Abstract】 In view of actual problems in pipeline laying, based on the knowledge of geometric and extreme va-lues of multivariate functions, this paper analyzes different situations and establishes the optimization model respectively, to solve the coordinates of the joint point of common pipeline and non-common pipeline with the aim of finding the optimal pipeline laying scheme. Meanwhile, the optimal scheme and the optimal value of pipeline construction cost are obtained through solving coordinates of the urban-rural junction point.更多还原
