前期固结压力 meaning in English
preconsolidation pressure
Examples
- The research indicate that the structured soft clay has below several characteristic , the viscous strain is produced during the stage of primary consolidation and of second consolidation , and in the prophase , the relation of stress - strain - strain rate is unique , so the form of constitutive model , such as , f ( v ' , e ) = 0 , f ( ' v , e , t ) = 0 , ca n ' t describe strain behavior of soil skeleton rationally ; the time - dependent properties involve three aspects , in addition the time - dependent strain , apparent preconsolidation pressures that depend on strain rate , and the effect of creep compression on apparent preconsolidation pressures ; because of holding structural strength , the mechanics characteristic is determined by the magnitude of stress , and the compression curve is composed of several sections . by combining structural yield stress and it ' s characteristics with the improved time line model , a new one - dimensional elastic visco - plastic consolidation model is established
研究结果表明，结构性土的固结过程具有以下特性：主固结和次固结阶段都包含有因土骨架的粘滞性移动而产生的变形，而且在正常固结阶段，存在应力?应变?应变速率的唯一性， f ( _ v ， e ) = 0 、 f ( _ v ， e ， t ) = 0形式的本构关系不足以描述土骨架的变形行为；固结压缩过程中的时间效应包括三个方面的内容，除了应力应变关系与时间相关外，还包括粘滞性变形引起表观前期固结压力增加和屈服应力的应变速率效应；软土的结构性使其力学特性与应力水平相关，压缩曲线具有分段性。 - Criterion method of settlement calculating is also introduced in this paper . after comparing the calculating value of criterion method with the data which measured in - site , this paper points out : ( 1 ) settlement brought by side deformation should be taken into account among the super soft silt groundsill in pearl river delta area ; ( 2 ) stress history has a great deal influence to the settlement , but the pre - consolidation pressure pc for the judgement of consolidation state of soil has no credibiliy which is gotten in laboratory
此外，本文还简述了规范推荐的沉降计算方法，并运用已有的工程实测数据与规范方法计算值进行了比较，指出对于珠三角地区的超软弱地基。应考虑侧向位移引起的沉降；应力历史对沉降的影响较大，而判断土体固结状态指标的前期固结压力p _ c ，在试验室得出的数据并不可靠。 - Based on the new model , the influences caused by soil structure , apparent preconsolidation pressure , the re - compression index , the coefficient of secondary compression , the magnitude of loading , the coefficient of permeability , the rate of loading , the thickness of clay , the self - weight , the layered property etc , in the process consolidation of soil with structure , are analyzed in detail . the difference between the present model and yin & graham model was also given
基于本文新建模型，分析论述土结构性、表观前期固结压力、再压缩系数、次固结系数、荷载增量大小、渗透系数、加荷速率、固结层厚度、自重应力随深度变化和土体成层性等对土固结的影响，比较本文模型与yin & graham模型的异同，阐述土结构性和流变性对软土固结压缩行为的影响。
