Abstract：Abstract：Research purposes： With the large - scale use of shield method in subway construction, it is very important to reasonably determine the specifications and size of shield segment in the design. Currently， the built or under construction subway tunnel segments design often use more engineering analogy at home，less on the system analysis and research of segment specifications，and has not yet formed a comprehensive set of design methods on a variety of factors. Based on the shield tunnel design of Taiyuan metro line 2，combined with hydrogeology condition and engineering characteristics，this paper analyzed and studied of the determination basis of segment specifications，the structure form， diameter and thickness and erection method of segment. the conclusion has important guiding significances to the subsequent shield tunnel design in Taiyuan metro.
Research conclusions:(1) For the A vehicle，the inner diameter of 5 500 mm segment can fully meet the requirements of limits. (2 ) Segment ring width by 1.2 m has little increase in the overall investment，and provides inclusiveness for the subsequent small radius lines. (3 ) The results can be applied in the structure design of shield tunnel in Taiyuan Metro Line 2.
