soil swelling pressure

基本解释

It is understood that the existence of large amount of swelling pressure in the slope due to rainfall changes the expansive soil slopes' stress and strain distribution.
膨胀土路基边坡在持续降雨后常常出现大面积表层滑坍失稳，造成巨大的经济损失。
A site including expansive soil layer with high swelling pressure is chosen to illustrate the influence of thickness and position of expansive soil layer on upheaval deformations.
对一个含高膨胀压力的膨胀土层的场地计算了地面上抬变形，以说明膨胀层位置及厚度对地面上抬变形的影响。

On this foundation, the determination method of treatment depth for subgrade paved with expansive soil is proposed based on the relationship of swelling pressure and unloaded expansibility.
在此基础上，建议按膨胀力与零膨胀率的相关性来确定膨胀土路基处置深度。
