Chapter four basing on the analyze of the pavement bearing strength using winkler subsoil model , modulus back - calculation was done through the fwd dynamical basin 第四章在采用winkler地基模型來分析路面承載力的基礎上,利用fwd的動態彎沉盆進行模量反算。
Aimed at this property hi which the effect of visco - elastic parameters appeared in late period , this paper proposes that parameters are not adopted as basic ones to predict settlement unless this computed parameters are similar in the course of back - calculation 針對粘彈性參數對沉降的影響在固結后期才能明顯表現,提出通過對不同時間段觀測信息反演獲得的計算參數基本一致時,才可作為沉降預測的基本參數。
According to the pavement structure dynamical analyze theory , the principle and process of the pavement modulus back - calculation have been discussed . the appliance ideas of the dynamical modulus among the pavement evaluation , the dynamical characteristic and correlative dynamical parameters of the cement concrete pavement surface , basement and subsoil have been investigated , and the contrast relationships between dynamical and static modulus of the cement concrete pavement have been established , and the evaluation standard of the structure layers " dynamical modulus of the cement concrete pavement has also been presented 根據路面結構動力分析理論,對路面模量反算的原理及實現過程進行論述,研討了動態模量在路面評價中的應用思想及水泥混凝土路面面層、基層、土基的動態特性和相關的動力參數,建立了水泥混凝土路面動態模量與靜態模量的對比關系,提出了水泥混凝土路面各結構層動態模量的評價標準。
As to planar visco - elastic prediction of settlement , this paper fixes on range of the back - calculation parameters range , analyzes back - calculation parameters which are indispensably in the course of anti - analysis . since it is difficult to acquire the optimization result in simultaneous back - calculation , this paper puts forward a calculation method which combined with investigation data and field experiment data to minimize the parameters to get optimization ( 2 )針對二維粘彈性沉降預測,確定了模型反演參數的取值范圍,對于多層軟土地基變量同時反演很難獲得最優解的問題,提出結合工程勘察和現場實驗以減少參數的方法獲得最優解。
