中文摘要 | 本文利用電滲透壓密理論,建立電滲透強度預測模式,並配合現地試驗案例、室內試驗案例及電滲透室內試驗的結果,驗證電滲透強度預測模式之適用性,同時藉由電滲透室內試驗成果,建立電滲透地盤改良行為機制,並以電滲透添加鹽類試驗結果與電滲透試驗作一比較。研究成果顯示:電滲透壓密為電滲透試驗及電滲透添加鹽類試驗之強度增加主要來源,但電滲透試驗在正極附近含有電化學效應,而電滲透添加鹽類試驗之電化學效應,則涵蓋整個改良區域。因此,電滲透強度預測模式,適用於電滲透不含電化學效應之區域,若改良區域含有電化學反應,則模式預測值會有低估試驗改良強度的情形;所以欲完全準確的預測電滲透地盤改良強度,除了電滲透壓密外,必須涵蓋電化學反應的因素。此外,本文亦藉由室內試驗結果,觀察電滲透過程中土壤電阻值變化情形,建立了電滲透地盤改良三階段之行為機制。 |
英文摘要 | In the article the authors developed a strength prediction model for the electro-osmosis ground improvement based on the electro-osmosis consolidation theories. The article then investigated applicability of the strength prediction model to ground improvement by way of in-situ tests and laboratory experiments. The laboratory results were also used to establish the behavior mechanisms of the electro-osmosis ground improvement. The results show the effect of electro-consolidation is a primary source of strength increment for electro-osmosis test and electro- osmosis additive salinity test. Area near the anode in the electro-osmosis test and entire area in the electro-osmosis additive salinity test exhibit phenomenon of electrochemical reaction. The proposed electro-osmosis prediction model can accurately predict the strength for the area without the electrochemical effects. On the other hand, the electro-osmosis prediction model underestimated the improvement strength if the electrochemical effects are observed. These electrochemical factors cannot be described only using conventional parameters of soil mechanics. To accurately predict ground improvement strength, electrochemical effects must be included. Besides, the three phase behavior mechanism of electro-osmosis is established based on the change of electric resistance in the soil induced by electro-osmosis improvement, according to the results of laboratory tests. |
