| 摘 要： | 本文用弹塑性大应变的有限无法对几种不同介质中均匀胀膨球的应力、应变和位移场作了计算。得出了松软表层、软弱夹层和软弱包体对应变、位移的影响,并对前兆优显层的存在进行了讨论。

| Abstract: | A computer program of isoparametric finite element for large elastis-plastis strain was used to calculate the displacement-strain fields of a ho-mogeneous expansive sphere in many-layer medium.The effects of the soft layer on diaplacement-strain fields and precurson of earthquakes were stu-died.Finally,we discussed the problem of obvious seismo-precurson layer. |
