地裂缝一旦形成，它便同梯田中的黄土陷穴一起成为地表水转化为地下水的通道。

Once the ground fissure forms , it contributes to the passage of surface water to the groundwater system .

岩床底上如有陷穴，就起到天然溜槽的作用，干扰了岩流体系，使硫化进一步堆积。

Sulfide further accumulates where depressions in the bottom of the sill interfere with the flow system and act as natural riffles .

简要阐述了公路路基施工技术中的路基填土与压实、路基路面排水、路基防护、软土地基处理、黄土陷穴处理等常用的相关措施。

The roadbed fill and compaction , roadbed drainage and pavement drainage , roadbed protection , mollisol roadbed handling and loess sink handling etc. conventional relative measures in highway roadbed construction technology are simply elaborated .

已建和在建的黄土地区的很多隧道出现了地表变形灾害，黄土隧道的地表变形一般有以下三种类型：地表裂缝，地表塌陷和陷穴、落水洞。

Ground deformation diseases arise in building and built tunnels in loess area . The ground deformations in loess tunnels are divided into three types , namely ground fracture , ground collapse and settlement pit , and ponor .
