- 报道苏丹喀土穆炼油厂工程大体积混凝土结构的施工经验。为了控制大体积混凝土浇筑后内部温度升高，防止产生裂缝，在施工和养护过程中，采取了减小内外温差、改善约束条件、降低温度应力、以合理的顺序浇筑、加强施工组织和现场管理等一系列措施，使高温沙漠地带大体积混凝土的施工获得成功。
The experience in large volume concrete placement on Khortum Refinerty project in Sudan is presented. To control the increase in temperature inside the concrete after placement and the formation of cracks, a series of measures were taken during concrete placement and curing, improve restraint condition, place concrete in reasonable sequence, and strengthen the construction orgaiization and on-site management, bringing the successful placement of large volume concrete in desert area.1999,6(6): 18-21 收稿日期：1999-1-25分类号：TU755
