　　地铁地下车站一般为狭长形状，其标准段变形以横截面上的平面变形为主，因此通常采用二维平面模型进行分析，但对盾构端头井段等部位，由于其受力具有典型的空间特性，荷载-结构平面框架计算方法无论在精度或可靠度上都达不到设计要求，因此，需建立空间整体模型对其进行受力分析。本文介绍了端头井计算模型和计算中存在的问题，探讨了端头井的分析计算方法，并通过实例详细介绍了端头井空间三维计算模型的建立、荷载的组合、荷载图式、约束条件等，运用软件对模型进行了计算，对计算结果进行了分析，得出的结论对类似工程的设计有一定的参考价值。

Metro underground stations are generally long and narrow, the deformation of the standard section is mainly the plane deformation of the cross section, therefore we usually use two-dimensional model for analysis, but for the shield section and other parts of the end well, because its stress has typical spatial characteristics, load-structural framework calculation methods can not meet the design requirements of accuracy and reliability, therefore, we need to establish space overall model to analyze its stress. This article describes the problems existing in the calculation models of end well and calculation, and discusses the computing calculation method of end well, through examples describes the establishment of spatial three-dimensional computing model of end well, load combinations, load pattern, constraints conditions etc., uses software to calculate the model, analyzes the results, the conclusion has a certain reference value for the design of similar projects.
