The results indicate that dynamic characteristics of upper layer soil are major factors that affect the complex stiffness of pile. Pile stiffness increases and damping decreases with increasing modulus of upper soil.
通过参数影响分析研究发现,成层土中桩顶复刚度主要受上部土层动力特性及性质影响;随着上层土模量增大桩顶复刚度的刚度部分也相应增大,阻尼部分相应减小。

Beneath the soil lies a layer of bedrock.
土壤下面有一层基岩。
The water evaporates and the salts are left behind, creating a white crustal layer that prevents air and water from reaching the underlying soil.
水蒸发留下盐分，形成白色的地壳层，阻止空气和水进入下面的土壤。
Once the humus layer disappears, nutrients cannot be recycled and leach from the soil, converting soil from fertile to infertile and making it suitable only for savanna vegetation.
一旦腐殖质层消失，养分就无法从土壤中回收和过滤，致使土壤由肥沃变为贫瘠，只适于热带草原植被的生长。
