較軟巖層 的英文怎麼說
中文拼音 [jiàoruǎnyáncéng]
較軟巖層
英文
rather yielding rock formation-
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。It ' s a kind of dead soft - rock with some special characteristics of muddiness, softenness, dehydrate and rift etc when it meet water. however, the articles about the socketed piles in this stratum had not been discovered
昔格達組泥巖在四川境內的西昌、攀枝花地區分佈較為廣泛，該巖層具有遇水泥化、軟化和脫水開裂等特徵，屬極軟巖類。It makes decision on stability state of countryrock according to in - situ surveying datum, and grey prediction model is formed using the deformation curve of country rock. this model can predict latter displacement of country rock. deeper analysis is also been counducted on countermeasure and mechanism of softrock tunnel, and gradation analysis method is applied to select the optimum bracing plan
再結合現場實測資料對地下洞室圍巖的穩定狀態進行判別，利用圍巖變形曲線建立灰色預測模型，採用該模型對圍巖位移的後期變形進行預測。對軟巖隧道的支護對策、支護作用機理進行了較深入的分析研究，並利用層次分析法選擇最優的支護方案。The nancha suspending - gay bridge of the changjiang road - bridge in jiangshu runyang, with a main span of 1490m, ranks first in china, third in the world. the north rivets, only 250m from the main stream of changjiang, have a tight liaison with the waterpower of it. especially, in this area, the face of rocks undulates a lot and exist fault - fabric. the soil there has apparent difference with the trend of water. the base - hole of north rivets can be named a super - deep one, with a 60m length, 50m widths, and 48m depths. the fence of the base takes advantages of the rectangular underground continuous wall structure and succeeds
江蘇潤揚長江公路大橋南汊懸索橋，主跨1490m ，居中國第一，世界第三。該橋的北錨碇距長江幹流僅250m ，與長江水力聯系密切，錨碇區水文、地質情況復雜，表層淤泥質土及松軟粘土層較厚，基巖頂面起伏較大，且存在斷裂構造，土層具明顯的流變特性。北錨碇基坑為長60m 、寬50m 、深48m的矩形超深基坑，其基礎圍護在國內首次採用矩形地下連續墻結構，並獲得成功。The data from xinbi high - slope shows that it ' s a stable slope. 3. the result of elasto - plastic finite element analysis shows that : ( 1 ) excavated - slope face would induce loose belt in rock ; ( 2 ) horizontal ground stress, joined rockmass and weak sandwich would make great unfavorable influence on slope stabilization and axial force of rock bolt
有限元數值分析結果表明：邊坡的開挖會使坡面巖體產生松動帶；構造水平地應力、結構面、軟弱夾層對坡體穩定及支護在坡體上的錨桿的受力情況有較大的不利影響。Based on development platform and the software designing, we develop a self - governed and perfect database system for surface wave tomography in china and its adjacent land and sea areas. this database system is helpful and important for probing into the deep earth, the form and evolvement of lithosphere / asthenosphere, the form and evolvement and the relation of surface structure and deep structure of chinese continent
為對這些海量數據進行合理有效管理，作者採用發展較成熟的開發平臺和軟體設計方法，開發一個獨立、功能完善的「中國及相鄰陸域海域面波層析成像數據庫系統」 ，對研究地球深部過程，對了解中國及鄰區邊緣海巖石圈軟流圈形成及演化，了解中國大陸形成及演化以及地表構造與深部結構的關系都具有極大幫助和重要的意義。On the pulling anchor - cable step, the internal force of beam - on - foundation can be calculated by winkler hypothesis in the case of weak rock mass and infinite half elastic foundation hypothesis in the case of stratums that are of some elastic characteristics
在張拉階段，可以採用溫克爾假定計算破碎軟弱巖體上的地梁內力；對于有較好彈性性質的地層，則可按彈性半無限體地基計算地梁內力。Being calculated, the frame beam - on - foundation may be disconnected to two single beams. on the pulling anchor - cable step, the internal force of single beam - on - foundation can be calculated by winkler hypothesis in the case of weak rock mass and infinite half elastic foundation hypothesis in the case of stratums that are of some elastic characteristics. the internal force of frame beam - on - foundat
在張拉階段，對于單片型地梁，可以採用溫克爾假定計算破碎軟弱巖體上的地梁內力；有較好彈性性質的地層，可按彈性半無限體地基計算地梁內力；對于框架型地梁，可按溫克爾地基模型計算其各單片梁的內力。分享友人
