三峡工程砂石系统的规划、建设与管理

三峡工程混凝土浇筑量大，强度高且持续时间长，砂石骨料的生产必须满足混凝土浇筑的要求。由于参建各方的努力，7年来三峡工程砂石料在数量、质量上基本上满足了工程建设的需要，得到了三峡工程质量检查专家组的肯定。回顾几年的工作，可得出以下几点，科学的规划、良好的设计是前提；选择有良好资质和实力的总承包单位是基础；先进的生产设备是保证；业主的科学管理是关键；参建各方的共同努力是确保工程顺利实施的根本保证。

Planning, Construction and Management of Aggregate Systems

The aggregate supply systems for the Three Gorges Project (TGP) must meet the requirements for concrete works with such features as huge volume, high placement rate and long construction duration. Because parties concerned have devoted a great deal of effort to the systems during the 7 year period, the systems basically can satisfy the construction demands in quantity and quality, and has been affirmed by the expert group to quality inspection of the TGP. The following conclusions can be drawn from the work for recent several years: scientific planning and elaborate design are a prerequisite; choosing a qualified and powerful general contractor is fundament; advanced production equipment is a guarantee; scientific management of the owner has a decisive effect and the joint effort by all parties concerned with construction of the project is a fundamental guarantee.
