满足多台盾构始发要求的工作井结构设计研究

Design and Research on Work Shaft for Several Shield Start

盾构工作井的尺寸应满足盾构机设备和安装的空间要求,对于需满足多台盾构下井拼装的情况,工作井的尺寸需考虑不同盾构机的尺寸及其交叉施工的影响。文中结合实际工程,分析多台盾构始发的结构尺寸要求,在满足结构尺寸要求的条件下对结构设计进行研究,通过工程验证,所提出的设计方法完全能满足结构功能要求。

The size of work shaft should satisfy the space of the equipment and installation of shield machine.To the case of the assemblage of several shield machines,the size of work shaft should be considered according to the influence of different size of shield machine and cross-construction.At first the article analyzes the size of work shaft satisfying the start of several shield machines,and then researches the structural design.By the verification of practical engineering,the design method of article can satisfy the demand of structural use,and can direct the design of similar engineering in the future.
