| dc.description.abstract | Terzaghi單向度壓密理論被廣泛的應用在工程界，然而Terzaghi單向度壓密理論之優點是解析解易求得﹔缺點則是低估超額孔隙水壓的變化。往後學者如Gibson等人便根據上述的理論缺失來進行修正，並於1967年提出飽和黏土的壓密方程式，即Gibson-England-Hussey（簡稱G.E.H.）壓密理論，為一非線性的偏微分方程式。其應用範圍不受限於小應變的情況。而其優點為假設條件較符合土壤壓密的實際情況﹔缺點則是無法直接求得解析解。但是由最近所發表的文獻中，可知已經能夠將G.E.H.理論的單向度壓密方程式予以線性化。
雖然G.E.H.理論已經可求得解析解，但是求解上卻太過於麻煩。故本論文研究的目的乃在於推導出土壤受動態載重時壓密度的速算公式，並與Terzaghi壓密理論比較，提供計算壓密沉陷的參考。 | zh_TW |
| dc.description.abstract | The merit of the Terzaghi theory is that the analytical solution can be obtained easily. How-ever , this theory sometimes underestimates the variation of the excess pore water pressure. Ano-ther theory proposed by Gibson et. al. is more realistic but more difficult to handle due to its nonlinearity.
This research try to derive a quick-estim-ation formula can calculate the settlement induc-ed by time-dependent loading. The results will be compared with these obtained by the Terzaghi’s theory. | en_US |
