Firstly , the characteristics of soft soil especially of the seashore ' s was recommended and the ordinary methods of foundation treatment and new techniques was carefully researched , so the suitable methods of coastal soft soil " foundation treatment was chose , and the new technique of coastal soft soil ' s foundation treatment was developed and advanced , which applied to binhai road in shenzhen , the result is satisfied , furthermore we introduce in detail them and their construction method ; how to accurately predict the ultimate settlement by use of the inchoate data always is a puzzled problem in foundation treatment , and also a key problem in high grade road construction . secondly the stress - strain curve of the coastal soft soil , general regulation of settlement of which and estimate method of ultimate settlement was studied in this paper , then the best method of prediction the ultimate settlement of coastal soft soil foundation was chose 本文首先闡述了軟土地基尤其是濱海軟土地基的特點(diǎn),對目前常用的軟土地基處理方法以及新技術(shù)進(jìn)行研究,從中比較、選擇適合濱海軟土地基處理的方法,并發(fā)展和提出了濱海軟土地基處理的新技術(shù),經(jīng)過在深圳濱海大道的實(shí)際應(yīng)用,得到了令人滿意的結(jié)果,并對濱海軟土地基常用的處理方法及其施工工藝進(jìn)行詳細(xì)地介紹;在軟土地基處理中,如何由早期實(shí)測資料更準(zhǔn)確地推求最終沉降量一直是一個(gè)困擾人們的難題,也是高等級道路建設(shè)中急需解決的問題,本文深入地研究濱海軟土地基的應(yīng)力?應(yīng)變關(guān)系、路基沉降的一般規(guī)律以及最終沉降量的預(yù)估方法,比選出了濱海軟土路基最終沉降量的預(yù)估方法。
The s - l - e experiment data for the eight binary condensed systems of fatty alcohol / fatty acid were treated by using the improved equation , and the equation was examined with experimental data . at the same time , we used ideal model to predict the tenary s - l - e of n - octadecane / lauric acid / stearic acid system , and we got an accurate result of the simple eutectic temperature . the relative error is 0 . 51 % comparing with the experimental result , so we will offer a method of prediction for quickly obtaining multicomponent system phase change materials this article calculated the pcms quantities and energy saving effect in theory , designed the experimental apparatus to measure the energy saving effect , and analyzed the temperature equalization action of the pcms by comparing experiment 利用這種方法,建立了適合醇-羧酸等系列二元體系的單參數(shù)margules方程,本文對醇-羧酸系列等8個(gè)二元凝聚體系的單參數(shù)margules方程的參數(shù)進(jìn)行回歸,并利用整個(gè)實(shí)驗(yàn)數(shù)據(jù)對模型進(jìn)行了檢驗(yàn),另外,本文利用理想狀態(tài)模型對一個(gè)三元體系18烷-月桂酸-硬酯酸相圖進(jìn)行預(yù)測,通過與實(shí)驗(yàn)數(shù)據(jù)進(jìn)行比較,預(yù)測的低共熔溫度與實(shí)驗(yàn)測定溫度較為吻合,其相對誤差為0 . 51 ,這將為快速獲取多元體系的相變材料提供預(yù)測方法。
