[提要] 參照已有的托換方法,提出了一種新的托換方法——擴(kuò)底墩坑式托換技術(shù),研究了該技術(shù)的適用范圍、受力特點、設(shè)計及施工要點,并介紹了其在實際工程中的應(yīng)用,分析了這種技術(shù)的科學(xué)性和合理性。
[關(guān)鍵詞] 擴(kuò)底墩 托換技術(shù)A new underpinned technique is presented according to some technique existing. This article has studied on the application range, the characteristics of supporting pressure, the key point of construction and design of this technique. Its legitimate and scientific feature about realistic engineering are analysed.
