capping thickness

The determination of the cover thickness of the submarine tunnel is very important,because it will be very dangerous if the cover thickness is too small,whereas the length,slope gradient and cost will be increased after a larger cover thickness is chosen.

江底隧道的覆盖层厚度十分重要。

In underwater tunnel construction,the cover thickness not only plays the decisive role in its security,but al- so is a leading factor determining the underwater tunnel s cost and length.

在水下隧道施工中,覆盖层厚度不仅对其安全性起着决定性作用,而且还是决定水下隧道造价和长度的主要因素。

In underwater tunnel construction,to confirm the reasonable cover thickness is the key in the technology.
