unstable soil 中文意思是什麼
unstable soil
解釋
不安定土壤-
As the increase of domestic high - rise buildings, more and more deep foundation trench supporting constructions have come into existence. among the general geographical condition of the urban district in qingdao, most of regions, which mainly consist of strong de composed rocks, are in quite good condition. except for the sandy soil and oozy soil along sea sides. but the development of rock cracks and breaking zones and unstable lamprophyre still exist, so blasting is needed during constructions of foundation trench. blasting have bad influence on the stability of slopes. moreover. the slope - liding has happened for several times, so the engineering project of foundation trench attracts more attention of people
隨著國內高層建築的發展，深基坑支護工程越來越多，綜合青島市區的地質狀況，除海邊有砂性土及淤泥軟土外，大部分地域巖土條件相對較好，多以強風化巖為主，但巖石裂隙發育，間或有斷裂帶和穩定性極差的煌斑巖穿插其中，基坑施工時需要爆破施工，對邊坡的穩定造成了不利影響，加之連續出現的幾次滑坡失穩事件，基坑支護工程越來越引起了各方面的重視。 -
The urban ecosystem is a complex of society, economy and nature that consists of urban population and many natural factors that include urban bio - community of plant, animal and microorganism, urban geology and landform, urban hydrology and water resource, soil resource. the urban ecosystem have not only the ecological process and function that is homologous with natural ecosystem but also characteristic and other opening, complex and unstable character
城市生態系統是是由植物、動物、微生物等城市生物群落、城市氣候、城市地質地貌、城市水文與水資源、土地資源等自然要素，以及城市人口等組成的社會、經濟、自然的復合體，既具有與自然生態系統相應的生態過程和生態功能，更具有自己的特性，具有開放性、復合性和不穩定性等特點。 -
As a whole, the research work of this dissertation can be summarized as follows : ( 1 ) based on the porous media elastic unstable theory, the interfering well flow model of soft soil two - layer structure underground confined water is inferred, and consequently, the basic dewatering calculation method of soft - soil two - layer deep excavation dewatering is inferred
具體研究內容如下： （一）從彈性多孔介質滲流理論出發，推導出二元結構承壓含水層群井干擾穩定流模型，進而導出軟土地區二元結構地層深基坑降水的基本計算方法。 -
Annual precipitation series about 50 years is stable and no period ; further, the climate drying and desertification are n ' t caused directly by the decrease of precipitation during the period of the research according to the relational analysis among precipitation temporal - spatial change, runoff, evaporation, potential evapotranspiration and soil water ; longyangxia reservoir which was built in 1986 does n ' t have influence on precipitation up to now ; but annual temperature series in gonghe is unstable, having a linear upward trend, and it increases about 0. 0247, 0. 0422 and 0. 0272c per year, and temperature rise must be having an influence on desertification, but there is a very little temperature change, so that the effect is very small ; annual potential evapotranspiration series is stable too, so climate change has little influence on plant water consumption. 2
在青海共和盆地，近50年的年降雨量序列是平穩的、無周期，其時空變化與徑流、蒸發、潛在蒸散和土壤水分的關系表明，氣候乾燥和嚴重的荒漠化不是由於降雨量減少直接引起，龍羊峽水庫對共和盆地年降雨量變化沒有影響；但是年氣溫序列是非平穩的，茶卡、恰卜恰和貴南的年氣溫平均每年升高0 . 0247 、 0 . 0422和0 . 0272 ，且氣溫升高2 ，年潛在蒸散增加57mm ，盆地內氣候逐漸變乾燥，但影響比較小；由於歷年潛在蒸散序列是平穩的，因此氣候變化對盆地的作物潛在蒸散的影響在研究期內是較小的。 -
Considering that the infiltration capacity curve can ' t express the actual infiltration capacity, the authors develop the surface runoff yield models that combine with the infiltration capacity curve, unstable raining process and antecedent soil moisture in each rainfall or over a duration time
考慮到流域實際的下滲能力，建立了將下滲能力曲線、不穩定降雨過程和前期土壤含水量有機聯系起來的流域場（時段）暴雨地表徑流計算模式。 -
The surfacial sediment on the yellow river delta is so sensitive to ocean hydrodynamic condition, especially waves that soil failed and came into being a lot of unstable features : bumps and hollows, flute and groove cast of silt and collapse
黃河三角洲潮灘淺表層沉積物由於對海洋動力尤其是波浪作用的敏感，會發生破壞，形成塌陷、凹坑、粉砂流沖溝等一系列災害地質現象。 -
In order to simplify the computation and be advantageous for the theoretical analysis, the soil partial heat transfer analysis uses the unstable condition heat transfer model analysis research regarding the drill hole outside
為了簡化計算，便於理論分析，對于鉆孔以外土壤部分的傳熱分析，需要採用非穩態的傳熱模型分析研究。 -
Underground water seeping in, as the water makes the sandy soil unstable it is not possible to continue excavating, thus the excavations came to a halt
地下水位冒出，由於水量豐富，導致界墻上的沙質相當容易崩塌，難以進行更深入的挖掘，因此暫停。
