water-free soil

基本解釋

The results further our understanding of soil-water interaction under shaking, and provide the data for validating the analytical methods of the seismic response of free ground.
研究結果增強了對振動過程中土-水之間相互作用機理的理解，同時為自由場地震響應分析方法的驗證提供了基礎數據。
The program is utilized to calculate soil rocks dam free surface position variation and pore-water pressure distribution condition with time when the up water level position changed.
利用所編寫的非穩(wěn)定滲流計算程序，計算土石壩上游水位變化時自由面位置隨時間的變化規(guī)律、孔隙水壓力的分布情況。
The factors that can influence the soil seasonal free zing and thawing include snow -cover, vegetation, the soil component and contain water, the condition of earth, landform and so on.
土季節(jié)凍結和融化的影響因素主要有雪蓋、植被、土壤成分及含水量、地表狀況和地形等。
