| 摘 要： | 对软弱岩石(体)的流变特性进行了许多研究，相比较而言。对坚硬(相对)完整岩石流变特性的研究则少得多。坚硬完整岩石的流变特性对岩土工程的影响在很多情况下可以忽略。但在长期恶劣环境作用下，例如。长期浸泡于水中呈水饱和状态。其影响则会大许多。因而了解坚硬完整的岩石在恶劣环境作用下的流变特性，是很有意义的。鉴于此。开展了花岗岩在饱水状态下流变特性的试验研究。并与其风干状态作了对比，在强度和变形特性方面获得了重要的资料。

| Abstract: | A lot of experimental studies have been made on the rheological properties of soft rocks. Compared with this fact,only a very small quantity of studies have been done on that of hard and integrate rocks. The influence of rheological properties of hard and integrate rocks on geotechnical engineering can be omitted in many cases. However,the influence may be great enough so that it can not be omitted when hard and integrate rocks are in a very bad environment for a long time,for example,submerged in a saturated state. Therefore,the study of rheological properties of hard and integrate rocks is of great significance in a very bad environment. In this paper,rheological experimental study of granite is done in a saturated state,and comparison is made with that of air-dried state. Important data are obtained about strength and deformation properties of granite in the given condition. |
