摘要
指出了多绳提升机井塔设计中塔身的选型 ,对于大、中型塔身 ,宜选用钢筋砼箱形或外箱内框形 ,小型井塔可采用框架结构等形式。钢筋砼箱形或外箱内框形井塔塔身的静力计算可采用“悬臂梁”假定分析法 ,亦可采用有限单元法按空间结构分析计算。钢筋砼箱形或外箱内框形井塔基础的选型 ,应根据地基条件、平面尺寸布置等实际情况 ,选用天然地基上的基础、桩基础或井颈基础。在井塔的设计与实践中 。
The model selection in the design for multi rope shaft tower is presented in this paper. For large and middle shaft tower, it's suitable for selecting the model of reinforced concrete box or internal frame and external box. For small shaft tower, the frame structure can be used. For static force calculation of reinforced concrete box or internal frame and external box, cantilever beam analysis can be adopted, finite element method based on the space structure can also be used. The ground, pile and shaft neck should be used for the model selection of reinfoced concrete inertal frame and external box according to the ground condition and layout size. There are still some issues left to be further studied concerning design of shaft tower.
