Ultimate Bearing Capacity(極限承載力)是岩土工程領域的核心概念,指地基土體在發生剪切破壞前所能承受的最大荷載值。其物理意義為地基由彈性變形階段進入塑性破壞階段的臨界荷載,是工程設計中對地基穩定性評估的關鍵指标。
從力學機制分析,極限承載力由三部分構成:
其中$gamma$為土體重度,$B$為基礎寬度,$D_f$為埋深,$c$為粘聚力,$N_c$、$N_q$、$N_gamma$為承載力系數。
美國土木工程師協會(ASCE)在《Foundation Design Standards》中明确規定了不同土質條件下的承載力計算方法,特别強調需通過現場試驗(如平闆載荷試驗)與理論計算(Terzaghi公式、Meyerhof公式等)相結合的方式确定最終設計值。中國《建築地基基礎設計規範》(GB50007)要求采用分項系數法進行承載力驗算,确保安全系數大于2.5。
實際工程應用中,需重點考慮地下水位變化、荷載偏心距、地震液化等影響因素。例如飽和黏性土地基在長期荷載作用下的固結沉降會顯著降低有效承載力,此時需采用有效應力分析法進行修正計算。
ultimate bearing capacity(極限承載力)是工程學中的專業術語,尤其在土力學、結構工程和機械設計領域廣泛應用。以下是詳細解釋:
ultimate bearing capacity指地基、基礎或機械部件在完全破壞前所能承受的最大載荷。例如:
在土力學中,常用太沙基(Terzaghi)公式計算地基極限承載力: $$ q_u = cN_c + qN_q + 0.5gamma B N_gamma $$ 其中:
如需進一步了解實際工程案例或具體參數選擇,可參考機械工程手冊或土力學教材。
