shield tunneling method meaning in Chinese
盾构法隧道
Examples
- Application of shield tunneling method in beijing metro line
盾构法施工在北京地铁5号线的应用 - In this paper the stress - strain and deformation characteristics of loess of the fifth tunnel of luohuiqu were analyzed by means of conventional tri - axial tests and the softening constitutive models were established . the models provide not only the basic and the necessary calculation conditions to analyze the mechanics response and construction optimization of simple shield tunnel method on the fifth tunnel of luohuiqu , but also a new method in researching the softening constitutive models of loess
本文通过对洛惠渠五洞q _ 1黄土进行常规三轴试验，分析和探讨黄土变形强度特性，建立q1黄土的软化本构模型，这不仅为洛惠渠五洞的简易盾构法施工的力学响应分析及其施工优化提供了最基本，最需要的计算条件，而且为当前土力学研究的热点? ?土的软化本构模型拓展了新的思路。 - The famous project of gas transiting west to east and the cross - river tunnel of huangbu river in shanghai also will be constructed with this technique , which is under the plan . among the shield tunneling methods , up to now , earth pressure balanced shield tunneling ( epbs ) is the most universal type , and it is very certain that the epbs method adopt to our country increasingly . the key factor to success in epbs is converting the muck which is lack of fluidity excavated from the cutter face to the plasticity soil . but when the shied tunneling machine advancing , it is considerably difficult to reach this requirement because of the ground soil condition , which is consist of stiff clay , silt , weathered rock , and so on
近些年来我国城市地铁建设迅速发展，盾构施工法作为一种安全而又环保的施工方法得到了广泛的使用，另外在黄浦过江隧道，西气东输的穿黄隧道等工程也在使用盾构隧道施工技术。这其中土压平衡式盾构在我国的使用最为普遍，成为地铁隧道施工技术的主流。土压平衡式盾构施工成功的关键是要将开挖面切削下来的土体在压力舱内调整成一种“塑性流动状态” 。
