次等地槽 的英文怎麼說
中文拼音 [cìděngdecáo]
次等地槽
英文
miogeosyncline-
In the process of work, according to complex geological conditions such as huge thick soft clay in site and top surface of possible pile foundation supporting course fluctuating in large amplitude, we adopted many advanced exploratory methods ( just as high accuracy exploration of shallow earthquake, crosshole wave velocity test, vane shear test, pressuremeter test, etc. ), we found out that there is an ancient groove of yangzi river in former plant site, therefore we suggested in time that plant site should properly be moved eastwardly, only this item saved nearly about 50 million for pile foundation project cost
在工作過程，根據廠址區軟粘土厚度大、可能作為樁基持力層頂面起伏變化大等復雜地質條件，採取了多種先進的勘探手段（如高精度淺層地震勘探、跨孔波速試驗、十字板剪切試驗、旁壓試驗等） ，查明了原廠址區存在一個長江古凹槽，並及時建議廠址適當東移，僅次一項就節省樁基工程費用近5000萬元。In this thesis, first, reasons and factors for the stability of loose rock dams were summarized according to the field surveys and certain expert ' s experiences. then, researches on block stability problems were reviewed, and according to the relationship between grain size and incipient velocity, it is found that the block weight is in direct proportion to 6 - 9 power of incipient velocity, and 50 % increase of the velocity will result in about 40 times change of the block weight. after that, experiments were conducted in a flume, focusing on the relationship between incipient velocity and some main factors including block weight, water depth over the dam, cross - section size, block material and river bed material
本文首先根據散拋石壩損毀情況的現場調查資料，結合有關專家多年的整治經驗，總結出壩體的損毀原因及影響因素；對現有塊體穩定性的研究成果進行回顧和總結，並針對散拋石壩的直接損毀現象，結合山區河流的水流、地形特點，利用塊體粒徑與起動流速的關系，提出塊體穩定重量與起動流速高次方成正比的概念，流速50的增長可能導致塊體穩定重量接近40倍的變化；通過二維變坡水槽試驗，研究了壩體穩定的主要影響因素，包括塊體重量、壩頂水深、斷面尺寸、塊體材料（塊石和卵石兩種） 、護底等，結果表明對于山區河流，試圖僅僅通過增加壩體單個塊體重量或斷面尺寸來提高壩體穩定性效果甚微；最後，根據西部地區的自然、經濟、交通等條件，提出可以採用柔性混凝土鉸鏈體等一類整體性較好的護面層作為散拋石壩的防沖毀措施，以期取得良好的工程效果。In the present paper, 3 tribes, 21 genera and 133 species known in asia - pacific area are diagnosed, of which 1 subgenus and 97 species ( including 5 species drabescus jinxiuensis, drabescus lii, drabescus lamellatus, fistulatus monkoboensis and fistulatus athena published in 2003 ) are new to science and 1 new synonym is proposed, 56 new species are from china, 6 genera and 6 species are recorded for the first time from china. they are listed as follows : new subgenus : hecaloidella ( adnascens ) subgen. nov. new species : hecaloidella ( s. str. )
本次研究共整理、鑒定和記述亞太地區緣脊葉蟬亞科3族20屬133種，包括1新亞屬， 97新種（其中蒙卡管莖葉蟬fistulatusmonkoboensis 、雅典娜管莖葉蟬fistulatusathena 、金秀脛槽葉蟬drabescusjinxiuensis 、李氏脛槽葉蟬drabescuslii 、片莖脛槽葉蟬drabescuslamellatus等5種已另文發表） ，確認1個新異名，其中中國15屬68種，包括33新種、 6個中國新記錄屬、 6個中國新記錄種。
