_ _ _ _ uncertain factors of macroscale inversion analysis of displacements are summed up . associated inversion model containing non - deterministic factors is proposed , i . e . " deterministic inversion of differential equation + systematic optimization technique = non - deterministic inversion " . the systematic optimization technique includes direct operator optimization , direct numerical analysis optimization , measurement design optimization , measured data processing , in - ersion algorithm optimization , and inverse operator regularization , etc . when this associated inversion technique is used in displacements back analysis , uncertain factors can be processed quantitatively 歸納了宏觀尺度位移反演分析的不確定性因素,提出了容納不確定性因素的位移反演分析的聯(lián)合反演模式,即“微分方程確定性反演+系統(tǒng)性優(yōu)化技術(shù)=非確定性反演”的模式,并具體論述了聯(lián)合反演模式的系統(tǒng)性優(yōu)化技術(shù),包括正演算子的優(yōu)化、正演數(shù)值分析的優(yōu)化、測(cè)量設(shè)計(jì)優(yōu)化、觀測(cè)數(shù)據(jù)處理、反演算法優(yōu)化、反演算子處理等六個(gè)優(yōu)化方法。
On the basis of the uncertainty load factors which influence embankment ' s settlement , the vehicle load and the step - exert construction load are studied by quantity . according to the terzaghi ' s consolidation theory , the average consolidation degree formulas of the corresponding situations are inferred . moreover , the feature of the embankment ' s consolidation in the effect of uncertainty load factors is studied 并且基于影響路基沉降分析的不確定性荷載因素,對(duì)車輛荷載及填土荷載逐級(jí)施加兩種情況進(jìn)行了量化分析:依據(jù)太沙基固結(jié)理論,推導(dǎo)了兩種情況下的土層平均固結(jié)度公式,由此分析和討論了不確定性荷載因素影響下路基固結(jié)的特性。
