土力學中的"固結度"(degree of consolidation)是指飽和黏性土體在外部荷載作用下,孔隙水排出導緻體積壓縮的完成比例。該參數由現代土力學奠基人Karl Terzaghi在其1923年發表的一維固結理論中首次提出,其核心公式為:
$$ U = 1 - frac{8}{pi} sum_{n=1}^{infty} frac{1}{(2n-1)} e^{-(2n-1) pi T_v/4} $$
其中$U$代表固結度,$T_v$為時間因數。根據美國土木工程師協會(ASCE)技術手冊,工程實踐中常采用簡化的近似公式$U = sqrt{frac{4T_v}{pi}}$(當$U<60%$時)進行計算。
在岩土工程領域,固結度是評估地基沉降速率的關鍵指标。中國《建築地基基礎設計規範》(GB50007-2011)明确指出,通過固結試驗測定該參數可準确預測建築物工後沉降量。英國帝國理工學院的研究顯示,現代監測技術結合固結度理論,能将軟土地基處理效率提升40%以上。
“Degree of consolidation”是一個工程地質學(尤其是土力學)中的專業術語,主要描述土壤在荷載作用下固結過程的完成程度。以下是詳細解釋:
基本定義
核心計算公式 固結度的經典理論公式為: $$ U = 1 - frac{8}{pi} sum_{n=0}^{infty} frac{1}{(2n+1)} e^{-(2n+1) pi T_v/4} $$ 其中,$T_v$為時間因數,與土層的滲透系數、壓縮系數和時間相關。
工程應用
影響因素
該術語常見于《土力學》教材和岩土工程規範中,實際工程中需結合室内固結試驗(如oedometer test)測定相關參數。
