thickness of soil meaning in English
土层厚度
土壤厚度
Examples
- If self - weight stress is assumed to be uniform , the settlement will increase with the increase of the value of ratio cc / ck , or the level of loading , or the thickness of soil
当假定自重应力为常数时， c _ c c _ k值、荷载和土层厚度的增加都会使沉降加大。 - The study shows that besides boundary conditions , the factors influencing the nonlinear consolidation behavior of soils are the compression index cc , the permeability index ck , the level and the rate of loading , and the thickness of soil , etc . in nonlinear consolidation , especially for layered soils , the average consolidation degree defined by settlement , us is greater than the one defined by effective stress , up , i . e . , the rate of the development of settlement is greater than that of the dissipation of excess pore water pressure
研究表明，除边界条件外，影响软土地基一维非线性固结性状的主要因素是压缩指数c _ c 、渗透指数c _ k 、荷载大小与加荷速率、土层厚度等。对于非线性固结，特别是成层地基，按沉降定义的平均固结度u _ s大于按有效应力定义的平均固结度u _ p ，即沉降发展速率要快于超静孔压消散的速率。 - Adopt the mean of analyzing the factors which influence the output of the crops to quantity and determine the factors , assess the correlation among the grading factors in the units and calculate the point value of these factors ; determine the weigh value of the factors . ten factors , which are content of organic matter , thickness of soil layer , quality of soil , pickled degree of land , condition of irrigation and state of shelter belt , the degree of land " s leveling , central focus region ( focus region location ) , utilization method of soil , are chosen as grading index at last
本文采用因素法定量化评价各地块定级单元的相关性和权重性，最终选定了有机质含量、土层厚度、土壤质地、盐碱化程度、排水能力、灌溉保证率、防护林完整度、条田平整度、中心区位，土地利用方式等因子作为定级的指标，使用了加权加和因素法进行了的定级计算，逐步完成了农用地质量情况的评价，划分出了级别。
