bottom soil meaning in Chinese
底土
Examples
- Analytic calculation of bottom soil resilience caused during excavation of a long strip foundation pit
长条形深基坑开挖引起基坑底土体的回弹解析理论计算 - But the correlation between co2 concentration in the bottom soil and temperature is not significant
随着土壤深度增加，这种相关程度降低。此外，土壤co 。 - But variation of the co ; concentration in the bottom soil show that sink effect of carbonate rock on the soil air co2 ( 2 ) the diurnal observation results of soil co2 dynamics in the different vegetation show that the soil co2 concentration in the bare land is sensitive to environment , but the soil co ; concentration in the other experimental site , which covered with vegetation , restrain the variation
在土壤?大气界面上，土壤表层可为大气提供游离co _ 2 ；而土壤深部co _ 2浓度的变化则显示下覆碳酸盐岩对co _ 2有吸收作用。 ( 2 )在不同植被系统中，土壤co _ 2昼夜动态变化进程不同。观测资料表明：裸地对外界环境的变化相当敏感，而有植被覆盖的竹林和草甸对土壤co _ 2浓度动态变化有平抑作用。 - In this paper , based on the characteristics of force and deformation of pars , the time - variation of the elastic coefficient of fulcrum in the calculation model of pars is analyzed and studied ; and the lessening of rigidity coefficient of elastic fulcrum , which is caused by the continual bottom soil resilience beside the piles and the increase of excavation depths during different steps , is discussed
摘要根据桩锚支护结构的受力和变形特点，研究分析了桩锚支护结构计算模型中支点弹性刚度系数的动态时变性；讨论了随桩内侧坑底土的持续反弹以及不同工况下随著基坑开挖深度的逐渐增大，进而导致弹性支撑刚度系数的减小的变化规律。
