1·Soil survey should be adopted in such soil overburden areas.

在此类土壤覆盖区应采用土壤测量。

2·During overburden stripping construction, we have successfully practiced excavation, graded stockpiling and comprehensive utilizing technology for soil layer, mud or muddy clay.

在该矿山覆盖层剥离施工中我们成功实践了土层或淤泥或淤泥质粘土挖运、分级堆放、综合利用技术。

3·The paper analyses the stress faced by the ecological system of Feiketu river basin due to project construction, vegetation damage, soil erosion, water pollution and overburden water use.

文章分析了蜚克图河流域工程建设、林草植被破坏、 土壤侵蚀、 水质污染、超负荷用水等使流域生态系统面临的威胁。

4·In this paper, a three-dimensional (3d) finite element (fe) model is developed to simulate the behavior of soil nail considering the effects of overburden pressure and dilation.

通过建立一个三维有限元模型，研究土钉在不同上覆压力和剪胀作用下的土钉抗拔行为。

5·Parametric analysis is carried out to investigate the effects of soil dilation and overburden pressure on the soil nail pullout resistance.

结果显示，当上覆压力较小时，剪胀角对抗拔应力的影响较小。

6·There are some earth caves and karst in the airfield runway subgrade of some newly constructed airport, and the bearing capacity of the overburden soil in the subgrade is low.

某新建机场滑行道路基中存在土洞和溶洞，且路基上部土层承载力低。
