tri axial strain
解釋
三維應變-
With the data recorded by computer, the author studies the experiment progress in detail, which includes the development of pore press, strain, strength of the sand, etc. connecting the development of these phenomena with the development of stress path, the author finds new mechanism which can explain the phenomena in the experiment. what is more, according to the dynamic test of the sand, there appears a steady state at the last phase of the development of strain and stress path, in which the strength of the sand is studied because it is an important parameter in evaluating the stability of sand against liquefaction. secondly, the dynamic constitutive relation was studied through the dynamic tri - axial test
本文首先採用目前國內較先進的微機控制動三軸儀，利用其可以適時採集和儲存數據的優勢，對砂土的實驗過程進行了細致的分析，研究該過程中孔隙水壓力發展、軸向應變發展以及它們與應力路徑之間的關系，對飽和砂土的剪脹、剪縮和卸載體縮等多個方面進行了研究，探索了砂土的動力特性，分析了影響砂土抗剪強度的各種因素，這些因素既包括土本身的特性（土的密度、結構、級配、透水性以及初始狀態等） ，又包括動荷載的特徵（振動力幅值大小和振動頻率等） 。 -
Some useful results were found after those. firstly, the softening and dilatancy characteristics of qi loess stress - strain were found by means of conventional tri - axial tests
通過研究，本文主要取得了如下一些有益的成果：首先，通過常規三軸試驗揭示了q1黃土的應力應變軟化和剪脹特性。 -
The pore pressure, relationship of stress and strain, and the shear strength parameters obtained by unloading tests are different from those obtained by loading tri - axial tests. later the difference is analyzed in the respect of stress path and microstructure. at last, by use of a practical project the author compared and analyzed the two sets of shear strength parameters obtained by two different stress paths
模擬基坑開挖的三軸試驗得出了與常規三軸試驗不同的孔隙水壓力和應力-應變關系，這樣得到的抗剪強度指標也低於常規三軸固結不排水加荷試驗所得抗剪強度指標，繼而本論文對抗剪強度指標的差異從應力路徑的角度和微觀結構的角度進行了分析。 -
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
本文通過對洛惠渠五洞q _ 1黃土進行常規三軸試驗，分析和探討黃土變形強度特性，建立q1黃土的軟化本構模型，這不僅為洛惠渠五洞的簡易盾構法施工的力學響應分析及其施工優化提供了最基本，最需要的計算條件，而且為當前土力學研究的熱點? ?土的軟化本構模型拓展了新的思路。
