关于大直径钢筋混凝土薄壁圆筒内抛石施工的分析

Analysis on Riprap Work in a Large-diameter Cylinder with Reinforced Concrete Thin-wall

随着港口建设日新月异的发展,大直径钢筋混凝土薄壁圆筒结构以其受力合理、结构简单、造价低等诸多优点脱颖而出。在大圆筒结构施工过程中,筒内抛石是一项重要工艺,以日照港某大圆筒码头筒内的抛石施工为例,对此工序进行分析,考虑当地施工条件的特殊性,进行了必要的技术处理。

With the rapid development of harbour construction, large-diameter cylinders with their reinforced concrete thin-wall become more and more popular for the reasona- ble stress,simple structure,lower cost and so on. Riprap work in the cylinder is impor- tant during the the engineering with the mentioned construction technology. This paper gives an example showing the riprap work in a large-diameter cylinder of Rizhao port. Due to the specificity of the local construction conditions, some necessary technological improvements have been made.
