pore water pressureとは 意味・読み方・使い方

Further, since the inflow port 12 for pore water is closed by the filter 30, it is possible to measure only the water pressure of pore water having filtered through the filter 30 to penetrate into the interior of the container 10.例文帳に追加

また、間隙水の流入口１２が透水フィルター３０により閉塞されているので、透水フィルター３０を透過して容器１０の内部に浸透した間隙水の水圧のみを計測することができる。 - 特許庁

To prevent the liquefaction of a permeable layer and surfacing of a sewage pipe and a manhole by reducing pore water pressure acting on the permeable layer, when pore water flows into the permeable layer during earthquakes.例文帳に追加

地震時に間隙水が透水層に流入した場合、透水層に作用する間隙水圧を低減し、透水層の液状化、延いては下水管およびマンホールの浮上を防止する。 - 特許庁

To provide a liquefaction test equipment allowing upward groundwater to generate excess pore water pressure in the ground for reproducing a liquefaction phenomenon.例文帳に追加

上向きの浸透流により地盤中に過剰間隙水圧を発生させて液状化現象を再現する液状化試験装置を提供する。 - 特許庁

To surely lead vacuum pressure to a vertical drain material at the end of horizontal drain material and to uniformly discharge pore water.例文帳に追加

水平ドレーン材の末端の鉛直ドレーン材まで真空圧を確実に伝え、満遍なく間隙水を排水する。 - 特許庁

To suppress liquefaction by suppressing a rise in excess pore water pressure or increasing a ground density, in terms of a cast-in-place pile.例文帳に追加

場所打ち杭において、過剰間隙水圧の上昇を抑えたり地盤密度を高めたりして液状化を抑制する。 - 特許庁

To provide a water permeability tester capable of accurately obtaining measurement results of a hardly water permeable rock bed material under a condition of high restraining pressure, high pore water pressure and a relatively low hydraulic gradient, the same as at a deep underground part.例文帳に追加

難透水性岩盤材料を対象とし、地下深部と同様の高い拘束圧、高い間隙水圧そして比較的低い動水勾配の条件下で精度良く測定結果を得ることができる透水試験装置を提供する。 - 特許庁

A pressure gauge, a flow meter and a temperature meter are installed in a ground water sampling pipe, thereby measuring the pressure in a flow in the ground water sampling process, the pressure when the flow is intercepted, and the flow to measure the pore water pressure and a coefficient of permeability simultaneously with sampling the ground water.例文帳に追加

地下水試料採取管路には圧力計、流量計及び温度計が取付けてあり、地下水採取過程でのフロー中の圧力とフロー遮断時の圧力及び流量を計測し、間隙水圧と透水係数を地下水試料の採取と同時に計測できる。 - 特許庁

Since the atmospheric pressure in the pipe 51 is lowered, the pore water pressure in the vicinity of the excavated ground surface 20 is lowered partially and the ground can be excavated under the state in which the atmospheric pressure of the workroom S is brought close to the atmospheric pressure.例文帳に追加

集水管５１内の気圧が低いので、気密作業室Ｓの気圧を大気圧に近づけた状態で、掘削地盤面２０付近の間隙水圧を局所的に低下させて掘削することができる。 - 特許庁
