浅谈长输管道施工作业带的优化设计

Optimum Design of Construction Scope for Long-Distance Transportation Pipeline Project

根据施工作业的实际情况,对影响施工作业带宽度的管径、沟槽开挖尺寸、管沟土方挖填量等因素进行了充分论证。为了提高经济效益和社会效益,在符合设计规范、满足工程要求的前提下,应对施工作业带宽度进行优化设计,降低投资及合理确定工程造价。

The influencing factors on the construction scope of long-distance transportation pipeline include the diameter of pipeline,groove excavation,pipe channel excavation and backfilling amount. Those factors are investigated according to the actual condition of construction scope of long-distance transportation pipeline. In order to enhance the economic and social benefits,it is important to optimize the design of the construction scope of long-distance transportation pipeline, reduce the investment and reasonably make the cost estimation under the preconditions for meeting the design criterion and the demand of construction.
