Firstly , the paper puts out the formulas used to calculate displacement by secant modulus , which think about the influence on lateral displacement 提出了飽和粘土利用割線模量法計算固結(jié)沉降,且考慮側(cè)向變形影響的公式。
The secant modulus is used to calculate final settlement of high - stacked soil , compared with the result of e ~ p curve , the error is in the limit of tolerance 同時將割線模量計算沉降的方法應(yīng)用到高填方自身作用下的最終沉降計算中,通過與應(yīng)用e p曲線計算的結(jié)果進行比較,其誤差在允許范圍之內(nèi)。
Empirical expressions of the total longitudinal strain and the secant modulus are given . in addition , the relationships of the increasing rate of the total second - stage strain and the decreasing rate of the secant modulus with the number of cycles are obtained respectively 給出了縱向總應(yīng)變、割線模量的經(jīng)驗公式,及其第二階段總應(yīng)變增長率、割線模量衰減率分別與疲勞壽命的經(jīng)驗公式。
The reliability of secant modulus method is validated in which final consolidation settlement is computed . the experience formula of coefficient of permeability ( k , 0 ) and pore ratio ( e ) is presented and the experience expression of coefficient of permeability ( k10 ) and strain ( ) is offered too . lt is important to modity the acquiring method of coefficient of consolidation , because the method embodies that strain and pressure of consolidation effect on coefficient of consolidation 本文首先驗證了用割線模量法計算軟土地基最終固結(jié)沉降的可靠性;其次得到了滲透參數(shù)k _ ( 10 )和孔隙比e的經(jīng)驗關(guān)系,并且更進一步給出了滲透系數(shù)k _ ( 10 )和應(yīng)變之間的經(jīng)驗公式,更重要的是對求取固結(jié)系數(shù)的方法給予了改進,該方法反映了固結(jié)系數(shù)隨應(yīng)變和應(yīng)固結(jié)壓力的變化規(guī)律。
During continuous loading , the loess ' s structure is destroyed completely at the point of the least secant modulus and the loess ' s deforming process goes into the third stage after it the experiential - analytical solution of the secant modulus of different stages is deduced and the influence of water content is analyzed 本文提出了即時割線模量的概念,認(rèn)為在荷載連續(xù)施加過程中,割線模量最小的點即結(jié)構(gòu)完全破壞點,此后即進入第三階段。通過分階段進行分析探討,得出了各個階段的割線模量的經(jīng)驗解析解,并分析了含水量對其產(chǎn)生的影響。
