中文拼音 [jìngxiàngzhènfú]
徑向振幅
英文
radial amplitude-
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） 。Second, the thermoelastic coupling vibration of cylindrical shell are discussed by means of the same method. the coupling coefficient, amplitude of temperature, initial displacement, ratio of length to radius and that of radius to thickness are main factors which influence the thermoelastic vibration of cylindrical shell ; the higher the coupling coefficient is, the lower the axial force, the axial stress and the axial moment are
其次，我們用同樣的方法研究了圓柱殼的非線性熱彈耦合振動，主要結論如下：影響圓柱殼非線性熱彈耦合振動的因素主要有耦合系數、溫度幅值、長徑比、徑厚比以及初始位移參數；耦合系數越大，軸向應力、軸向力以及軸向彎矩越小。
