摘要
都市為了追求生活或產業活動上的方便性,不斷提升其都市機能以進行更新。此一機能透過各項設施、設備的建設呈現。道路・鐵路・河川・上下水道・住宅・商店等各種完備的都市機能活化設施,滿足了人們使用上的需求。然而,因人口增加所導致的設施不足、設施老朽化的修繕改建、亦或面對地震、水災等自然災害帶來的毀損時,於防衛等層面上。皆產生了設施再建的需求。最初以平面土地利用方式所進行的再建設工程,時至今日已逐漸被各項設施建設所占滿,都市開始轉向地下空間尋求場地。隨著建設技術、施工機械、使用建材等性能的進步,造就了地下空間利用的可能性。本文將說明於近代都市更新計畫中,地下空間利用時所需之主要地盤改良技術的變遷與工法。將筆者本身參與過的設施施工經歷於此報告中說明。
英文摘要
Cities have been upgrading their functions for pursuing the convenience in human life and production activities. This pursuit is appeared to take the form of constructing structures and related facilities. Structures, such as buildings, roads, railways, river banks, drinking water, sewerage facilities and etc., were constructed to meet the human needs at times, however, the necessities to compensate problems, such as the aging of those facilities, the shorting due to population increase, the threat of earthquakes or floods, have repeatedly demanded the restructuring of those facilities.
Today, reconstruction seems to have at grade land fully occupied with structures, and therefore, the utilization of underground space is further anticipated. The improvement in construction technologies, construction equipment, and the development of new materials have been enabling to work in underground spaces.
This report addresses the changes and methods of soil improvement technologies primarily demanded by underground utilization in relation to recent city renaissance projects that the author was involved.
