The creep of the concrete might cause comprehensive effect on the structure, such as stress redistribution and pre-stress relaxation.To better understanding the significant influence of the creep on the structure, the restriction of the reinforcement should be taken into account.In this paper, the creep of reinforced concrete was studied based on designed experiment with different concrete mixtures and reinforcement configurations.And Dischinger model was used to analysis the experiment results.It was found that, with the increasing of reinforcement ratio, the creep of all concretes could be reduced with a trend that the difference of the creep property between concrete mixtures would be delaminated by the reinforcement.And suggestion was proposed to modify the Dischinger model to better consider the influence of firm structure formed by rebar.

摘 要：国家逐渐转变经济发展方式，优化经济结构，推进能源结构调整。同时，国家也正处于转换增长动力时期，煤炭经济不确定性因素逐渐增多。现在竞争压力日益增加，电煤成本压力越来越大，煤炭企业只有注重成本管控，积极转变经济发展方式，才能保持可持续发展，不断提高竞争能力。文章以国家能源集团准能集团黑岱沟露天煤矿运输队为撰写对象，分析研究实际可行的成本管控措施。 关键词：成本管控;重型自卸卡车 中图分类号
