在建立国际航运中心的道路上，上海面临着长江口深水岸线及土地达到了近乎饱和所带来的发展壁垒，增加港区已经成为必然。同时政府每年花费大量的资金去疏浚长江口的泥沙，若能充分利用长江口的疏浚土资源吹填到横沙东滩，进行资源整合，借力发展横沙东滩则有望再建一个上海港，其吞吐能力能够满足未来30年的发展需要。该实际问题所涉及的数学模型为Monge-Kantorovich问题。本文以该模型为基础，设计了一个计算吹填所耗费总能量的数值算法，以此来估算整个工程的耗费。

Shanghai is now facing a barrier on its way to become an international shipping center; the sham shoreline and land having already reached saturation point at the Yangtze River estuary. The vital way to solve this problem is to build new ports. Meanwhile, the municipal government has been injecting massive funds to dredge sedimentate the Yangtze River estuary. If those dredged sediments could be hydraulically filled in Eastern Hengsha Shoal, another Shanghai Port can be built there with integrated resources, the handling capability of which will be able to meet the shipping demand in Shanghai for the next 30 years. The mathematical model raised from the practical issues is Monge-Kantorovich problem, which had intrigued and frustrated mathematicians for 232 years. Based on Monge-Kantorovich Model, this paper has designed a numerical method of estimating the gross energy hydraulic reclamation needed to evaluate the expense of the entire object.
