南水北调中线总干渠渠道土石方调配平衡研究

Research on earth-rock excavation-filling balance of main canal of Middle Route Project of S-N Water Diversion

南水北调中线总干渠渠道工程的土石方开挖、填筑工程量很大,土石方调配平衡问题处理得合理与否,对整个工程的占地、投资等方面有较大影响。为减少工程投资和施工占地,根据总干渠渠道工程的长跨度特点,提出相应的土石方调配平衡规划的设计原则,利用线性规划技术研究了总干渠土石方调配平衡问题,通过建立数学模型并求解,得到合理、优化的土石方调配平衡结果,为南水北调中线总干渠渠道施工组织设计提供了可靠依据。

The earth-rock excavation and filling quantity of main canal of Middle Route Project of South-to-North Water Diversion is very large,and its treatment and excavation-filling balance have significant effect on the investment and land occupation.According to the features of long-span of the main canal,we proposed design principles for earth-rock treatment and excavation-filling balance,and analyzed the earth-rock treatment and excavation-filling balance by linear programming method.Through mathematic model calculation,the rational and optimized earth-rock treatment and excavation-filling balance scheme is worked out,providing reliable basis to the construction,organization and design of the main canal of Middle Route Project of South-to North Water Diversion.
