中文摘要 | 將生石灰樁埋設於高含水量之軟弱黏性地盤中,藉由生石灰材料與樁周土壤間一連串之吸水、放熱、膨脹與化學反應等交互作用,可有效改善軟弱土壤之承載力及降低壓縮性,且改良後之土體在充分脫水及鈣離子圈逐漸形成後,更具有強化地盤、降低震動效應及改善土層物理性質等功效。有鑑於此,本文針對高含水量之黏性土壤,於其中設置生石灰樁體,藉以探討樁周土壤在充分脫水及鈣離子強化過程中,土壤側向土壓力之變化機制,於實驗室中利用生石灰樁壓密儀進行相關之研究,期能對於生石灰樁降低軟弱黏性土壤側向土壓力之功效有進一步之瞭解,以作為工程分析及設計上之參考。 |
英文摘要 | Instaalling of quicklime pile in soft cohesive soil with high water content will result a significant improvement on bearing capacity of soil and reduce the amount of consolidation settlements. In addition, the composite soil also has the merit of reinforcement, which can reduce the ground vibration during construction and improve the physical properties of soil after hydration and cementation of quicklime. This paper reports some experimental results about the lateral earth pressure generated from the quicklime pile treated soil. The aim of the study is to understand the properties of the quicklime pile that reduces lateral earth pressure of soft cohesive soil. The results we obtained can provide an experimental base for engineering design and field construction. |
