中文摘要 | 本研究以高品質之取樣方式取得臺北盆地K1區之黏性土樣,以精密之試驗儀器及嚴謹之試驗程序進行試驗,期能對臺北粉質黏土之基本力學行為有更深入之認識;其中CRS壓密試驗結果可瞭解土壤於正常壓密及過壓密狀態下之體積變化情形及其滲透性質;CKUC、CKUE以及CKUDSS試驗則係依據SHANSEP之試驗程序進行,其結果可瞭解臺北粉質黏土於不排水情況下之應力應變及強度特性;本文分析其體積變化特性及不排水之應力應變行為,供作日後研究土壤模式之基礎。 |
英文摘要 | The purpose of this study is to understand the fundamental behavior of the Taipei silty clay. High quality continuous piston samples were taken from K1 zone of Taipei basin. Tests were carefully carried out. Constant-rate-of-strain consolidation tests were conducted to study the volumetric behavior under normally consolidated and over-consolidated states. K-consolidated undrained triaxial compression, direct simple shear, and triaxial extension tests were conducted by using SHANSEP procedures at various OCRs. These shear test results provide insightful information of the undrained stress-strain-strength behavior of Taipei silty clay. The paper presents not only the test results but also the interpretation of these results and its implication on modeling. |
