中文摘要 | 本研究之目的是以造成最小擾動的自鑽式壓力計來探討臺北軟弱黏土之不排水剪 力強度。研究結果發現自鑽式壓力計所得之不排水剪力強度值比現場十字片剪力試驗或三軸 不飽和不壓密不排水試驗所得之強度約高 100% 左右,。研究結果亦發現,自鑽式壓力計與 預鑽式壓力計所得之極限壓力相當接近;壓力計之極限壓力與圓錐貫入試驗之錐尖阻抗有相 當好的相關係數。最後本研究乃迴歸臺北軟弱粘土自鑽式壓力計之淨極限壓力值與一般強度 試驗所得之不排水剪力強度之關係式,以供工程分析使用。 |
英文摘要 | The purpose of this study is to investigate the characteristics of the undrained shear strength of the Taipei silty clay using the self-boring pressuremeter apparatus. It is found that undrained shear strength ob-tained from the self-boring pressuremeter is about 100% higher than that from the conventional shear strength tests. Results also indicate that the ultimate pressure from the self-boring pressuremeter is close to that from the pre-boring pressuremeter. The ultimate pressure from the pressuremeter that has a very good correlation with point resistance from the cone penetration that. An empirical equation based on regres-sion analysis of self-boring pressuremeter tests as well as conventional shear strength tests is proposed. |
