| 8. | In this paper , some present experimental methods of shear strength parameters are briefly described and the shortcomings of them are pointed out . then in order to obtain the right shear strength parameters for design of deep pit excavation , the author did a lot of normal tri - axial cu experiments and tri - axial cu tests that can simulate the actual process of excavation using soil sample of different depth 本论文首先介绍了现有一些确定土体抗剪强度指标的方法及其适用范围并指出不足,然后从正确确定适合基坑设计中土体抗剪强度指标的角度出发,对不同深度下各层土体分别进行常规三轴固结不排水试验和模拟深基坑开挖过程应力路径的固结不排水卸荷试验。 |
| 9. | Some problems from the principal stress axis rotation experiment with hollow cylinder apparatus are analyzed in detail herein ; which consists of three aspects , such as the preparation of the hollow cylinder sample and the acquisition of the isotropic one ; the estimation and elimination of the size effect and the end effect in the experiment ; and the membrane penetration effect on both the drained and the undrained tests results , etc 摘要详细分析了采用空心圆柱仪进行主应力轴旋转试验遇到的若干问题,主要包括三个方面:空心圆柱试样制备及各向同性试样的获得;试验中尺寸效应、端部效应的考虑与消除;空心试样膜嵌入效应对排水、不排水试验结果的影响等。 |
| 10. | By doing single fracture drainage experiments , this paper has successfully presented the logarithm function relationship between ratio of drainage discharge through upward and plumb drainage hole and the ratio of their equivalent diameters . the drainage effect will be the best when the included angle between drainage hole and fracture surface is 21 ~ 36 4 、通过单裂隙排水试验,建立了倾斜孔和垂直孔的排水量之比与其交界线的等效直径比之间的自然对数关系式,排水孔排水量基本随其与裂隙面的交角减小而增大;对单组裂隙排水的初步分析表明,排水孔与裂隙面的夹角在21 ~ 36范围内排水效果最佳。 |
