大型混凝土筒仓的设计，国内大都采用普通钢筋混凝土结构，通过提高混凝土强度和加大仓壁厚度来满足裂缝控制要求，但实际效果不甚理想。采用无粘结预应力技术，不仅能有效地抑制裂缝产生，而且可取得较好的经济效果。本文以工程应用实例，对设计、施工的要点进行了探讨分析。并与普通钢筋混凝土结构方案进行了技术、经济对比。 In the design of large-scale concrete silos, most of the domestic use ordinary reinforced concrete structures. By increasing the strength of concrete and increasing the wall thickness to meet the crack control requirements, the actual results are not satisfactory. The use of non-cohesive prestressing technology not only effectively suppresses the occurrence of cracks, but also achieves better economic results. This article uses the engineering application example to carry on the discussion and analysis to the main points of design and construction. And technical and economical comparison with the ordinary reinforced concrete structure plan.
