infiltration n. 1.滲入;【醫(yī)學(xué)】浸潤(rùn)。 2.【軍事】滲透,通過(guò);滲透活動(dòng)。 3.【化學(xué)】滲濾。 advance by infiltration 滲透前進(jìn)。 an infiltration force 滲透部隊(duì)。
The results indicated that the higher the salinity of infiltration water was , the faster cumulative infiltration and wetting front increased , and more salt accumulated at the wetting front 入滲水的礦化度越高,土壤剖面含鹽量越高,且濕潤(rùn)鋒附近積聚的鹽分越多。
When the saline water ( < 3g / l ) infiltrated to 45cm , the top soil of 0 - 37cm was desalinized , when the saline water of 3g / l infiltrated , the desalinized depth was 0 - 15cm . moreover , sar of top soil increased with the sar of the infiltration water . 3 . through lab experiment , the characteristics of soil water and salt movement under different initial soil moisture content were analyzed 當(dāng)濕潤(rùn)深度為45cm時(shí),小于3g l的微咸水入滲后, 0 - 37cm土層處于脫鹽狀態(tài),而3g l的微咸水入滲, 0 - 15cm土層處于脫鹽狀態(tài), 15cm - 35cm土層含鹽量基本等于初始含鹽量,但濕潤(rùn)鋒處含鹽量很高。
The results were as follows : 1 . on the basis of saline water infiltration , the characteristics of movement of soil water and salt under different cumulative infiltration were studied . the results indicated that when the salinity of the infiltration water was 3g / l , the top soil was desalinized and salt accumulated at the wetting front 通過(guò)對(duì)不同入滲水量下土壤水鹽運(yùn)移規(guī)律的室內(nèi)模擬試驗(yàn)研究,結(jié)果表明利用礦化度為3g l水入滲后,土壤從上至下逐漸脫鹽,上層土壤含鹽量略低于土壤初始含鹽量,中間土層基本保持土壤初始含鹽量值,但濕潤(rùn)鋒附近發(fā)生突變,含鹽量達(dá)最大值。
Abstract : based on the data obtained from field observations and deformation monitoring , this paper deals with the deformation and failure of a double - decked slope composed of soft rock strata in its lower part and hard - brittle rock strata in its upper part . it is demonstrated that the deformation of this kind of slopes is always initiated by the non - homogeneous rheological compression of the lower soft rock strata , leading to the tension fracture and toppling of the upper hard rock strata , and at last the sliding of the whole deformed body will be caused by the shear failure along the stress - concentration zone in the lower soft rock mass under the actions of the gravitational loading and infiltration water 文摘:以現(xiàn)場(chǎng)考察和變形監(jiān)測(cè)資料為依據(jù),探討一個(gè)下部有軟弱基座,上部為硬脆性坡體的“二元結(jié)構(gòu)”邊坡的變形破壞問(wèn)題,揭示這類邊坡的變形總是以下部軟弱巖體的不均勻壓縮流變?yōu)橄葘?dǎo),進(jìn)而引起上部硬脆性坡體的拉裂與傾倒,最終通過(guò)滲入水的作用,使下部承載狀況已進(jìn)一步惡化了的軟弱巖體,沿剪應(yīng)力集中帶發(fā)生剪切破壞而導(dǎo)致整個(gè)變形坡體的下滑。
It is found that the degree of mineralization and metamorphic coefficient and conversion potential of formation water , the fault is zone of sluicing of atmospheric infiltration water flowing from basin west margin to east ( centripetal flow ) and sedimentary compaction water flowing from qija gulong depression to west ( centrifugal flow ) 通過(guò)地層水礦化度和變質(zhì)系數(shù)等參數(shù)的分布規(guī)律及一系列折算水位剖面圖的分析發(fā)現(xiàn),該斷裂對(duì)水是不封閉的,并且是盆地西緣大氣滲入水向東流動(dòng)(向心流)及齊家古龍坳陷沉積壓實(shí)水向西流動(dòng)(離心流)的共同泄水帶。
