土力学中的"固结度"(degree of consolidation)是指饱和黏性土体在外部荷载作用下,孔隙水排出导致体积压缩的完成比例。该参数由现代土力学奠基人Karl Terzaghi在其1923年发表的一维固结理论中首次提出,其核心公式为:
$$ U = 1 - frac{8}{pi} sum_{n=1}^{infty} frac{1}{(2n-1)} e^{-(2n-1) pi T_v/4} $$
其中$U$代表固结度,$T_v$为时间因数。根据美国土木工程师协会(ASCE)技术手册,工程实践中常采用简化的近似公式$U = sqrt{frac{4T_v}{pi}}$(当$U<60%$时)进行计算。
在岩土工程领域,固结度是评估地基沉降速率的关键指标。中国《建筑地基基础设计规范》(GB50007-2011)明确指出,通过固结试验测定该参数可准确预测建筑物工后沉降量。英国帝国理工学院的研究显示,现代监测技术结合固结度理论,能将软土地基处理效率提升40%以上。
“Degree of consolidation”是一个工程地质学(尤其是土力学)中的专业术语,主要描述土壤在荷载作用下固结过程的完成程度。以下是详细解释:
基本定义
核心计算公式 固结度的经典理论公式为: $$ U = 1 - frac{8}{pi} sum_{n=0}^{infty} frac{1}{(2n+1)} e^{-(2n+1) pi T_v/4} $$ 其中,$T_v$为时间因数,与土层的渗透系数、压缩系数和时间相关。
工程应用
影响因素
该术语常见于《土力学》教材和岩土工程规范中,实际工程中需结合室内固结试验(如oedometer test)测定相关参数。
