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 本文首先阐述了软土地基尤其是滨海软土地基的特点,对目前常用的软土地基处理方法以及新技术进行研究,从中比较、选择适合滨海软土地基处理的方法,并发展和提出了滨海软土地基处理的新技术,经过在深圳滨海大道的实际应用,得到了令人满意的结果,并对滨海软土地基常用的处理方法及其施工工艺进行详细地介绍;在软土地基处理中,如何由早期实测资料更准确地推求最终沉降量一直是一个困扰人们的难题,也是高等级道路建设中急需解决的问题,本文深入地研究滨海软土地基的应力?应变关系、路基沉降的一般规律以及最终沉降量的预估方法,比选出了滨海软土路基最终沉降量的预估方法。
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 利用这种方法,建立了适合醇-羧酸等系列二元体系的单参数margules方程,本文对醇-羧酸系列等8个二元凝聚体系的单参数margules方程的参数进行回归,并利用整个实验数据对模型进行了检验,另外,本文利用理想状态模型对一个三元体系18烷-月桂酸-硬酯酸相图进行预测,通过与实验数据进行比较,预测的低共熔温度与实验测定温度较为吻合,其相对误差为0 . 51 ,这将为快速获取多元体系的相变材料提供预测方法。
