| 内容記述 | The present research deals with the influence of local liquefaction in the surface ground on the underground structures by use of a linear finite element method. In the calculation, it is assumed that shear wave propagation velocity decreases with the degree of liquefaction. A summary of the results is given as follows. The distribution of the shearing stress and strain in the locally liquefied surface ground is very complicated. This is especially so in the liquefied area where the shear stress increases and the shearing strain decreases according to the degree of liquefaction of the adjacent area. In such a caisson structure that vibrates with the bed layer, the place in contact with the liquefied layer has a large shearing stress. On the other hand, in a tunnel structure that vibrates independently of the bed layer, the shearing stress and strain do not increase so much even if the layer in contact with it liquefies. The earth pressure acting on the structures is greatest when the surface ground incompletely liquefies and reverberates with an earthquake motion. From the above results, the authors think that the possibility of a resonance between a structure-ground system and an earthquake motion in a liquefaction process is very important. Furthermore, it is thought that local liquefaction of the surface ground has considerable effect upon the structures that vibrate with the bed layer. | |||||
