五洞 meaning in English

wudong

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。
