Tunnel construction is very difficult hi region with high geotectonic stress and high subsurface water pressure. few deep - lying tunnels are constructed in civil conveyance and hydropower engineering up to now
特別是對在高地應力、高地下水位區域的隧洞建設，其施工難度更大，在國內的水利水電工程建設中並不多見。 -
Under subsurface drip irrigation, soil wetted front movement when higher soil initial moisture content was quicker than that of when it is lower, so did the supplied water pressure and soil bulk density. the wetted front movement of clay loam was clearly slow than that of sandy soil, especially in the larger soil bulk density
地下滴灌條件下，初始含水量較高的土柱，濕潤鋒運移速度快于含水量較低的；在較高的供水壓力條件下，各個方向的濕潤鋒運移都比低水頭情況下的快；容重越大的土柱濕潤鋒運移速度越緩慢。 -
The water displacement experiment of carboniferous gas showed that under normal pressure natural gas in subsurface reservoir is difficult to migrate into minor pores and displaced water out the pores in reservoir
石炭系儲層氣驅水實驗表明，巖石滲透率與驅替后殘余水飽和度呈負相關指數關系。 -
The effectiveness of pressure seals in the subsurface may be evaluated by making a calculated fluidpressure profile of the overlying shales.
在地下，壓力封閉的有效性可以通過計算上層頁巖的流體壓力剖面來估計。 -
( 2 ) the emitter discharge of simple subsurface drip irrigation is greater than the infiltration rate after formed saturate loop in the short time. infiltration rate under subsurface drip irrigation is not only affected by soil texture, original soil moisture content and soil bulk density et al, but also by emitter discharge, which affect by water pressure
（ 2 ）地下滴灌的灌水器出流量一般在較短時間內形成飽和圈后，土壤入滲速率不僅受到土壤質地、土壤初始含水率、土壤容重等因素的制約，而且還與影響灌水器出流速率的壓力水頭有關。
