深成巖基帶
英文
hypobatholithic zone-
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 coqen basin in xizang lies between the bangong - nujiang suture zone and yarlung zangbo suture zone, and once extended northwards and southwards, respectively centred by the qiekan - goicang - asog rift zone as the center of deposition and subsidence during the middle jurassic to the early creatceous. ( 1 ) during the middle - late jurassic, the rift zone was occupied by deep - water turbidites, radiolarian siliceous rocks, shallow - water carbonate rocks, clastic rocks and basic - ultrabasic rocks, while both sides of it by littoral and shallow marine elastic rocks and carbonate rocks

( 2 ) in the area west to the shiwandashan basin, intermediate magmatites were controlled by deep ne - striking and nw - striking faults, especially at the conjunction site of these two group faults, magmatic activity was strong ; and its tectonic background can be attributed to extensional continental rift
其中，在十萬大山盆地以西地區的偏基性巖漿活動受北東和北西向深斷裂控制明顯，尤其以此兩組斷裂交匯處的巖漿活動強烈，盆地構造背景屬大陸伸展裂谷環境；在十萬大山盆地以東地區為偏酸性巖漿活動，主要受東吳運動形成的欽防造山帶的控制，屬大陸邊緣造山帶或島弧造山帶環境。( 2 ) taking the geology analysis as main way and combining the pre - test, predicating the tunnel ' s main geology condition ( rock quality, surrounding rock classification, long - wide joint, fault, ground water, crustal stress ), and predicating the main potential disaster ( collapse, breaking water, rockburst, large deformation ) ( 3 ) employing the stress test result and inverse analysis of the stress field, finding out the crustal stress " s distributing rule along the tunnel axes section : the highest crustal stress is 24mpa near the deepest spot, and predicting that the k2 + 260 ~ k3 + 000 likely to be the high crustal stress segment for this tunnel
通過地質分析、類比分析、監控量測、數值模擬、神經網路等方法，對鷓鴣山隧道潛在的主要地質災害（塌方、涌水、巖爆和大變形）進行了預測預報（ 3 ）在現場地應力測試成果的基礎上，運用數值計算進行應力場反演，基本查明了沿隧道軸線剖面的地應力分佈規律：地應力量級在最大埋深附近達到最大值24mpa ，並預測k2 + 260 k3 + 000段將很可能成為鷓鴣山隧道的高地應力段。 （ 4 ）塌方往往與斷層破碎帶及千枚巖相聯系。Alkali basite, which came from upper mantle or lower crust, invaded through those structure, which not only bring cu et al mineralizing elements, but also the most important is that thermal energy. it cycled the formation water ( yinmin fonnation and luoxue formation ), and form alkali - rich, middle - high temperature and salinity fluid mixed with alkali - rich magmatic water. there were high rate of percolation and well voidage in the contact zone between yinmin purple stratum and yinmin rubblerocks, which is in favor of the transposition and mineralization of minerogenetic fluids
因此，總結東川稀礦山式銅礦成礦模式為沉積（ fe 、 cu ） ?熱液疊加（ cu ）改造：晉寧-澄江期，小江深大斷裂發生走滑運動，在東川礦區造成右行旋扭及其派生構造，形成「 z 」字形落因破碎帶，同時來自深源（下地殼或上地幔）堿基性巖漿侵入，不僅帶來了大量cu等成礦物質，更重要的是提供了熱源，促使地層水（落雪組白雲巖和因民組紫色層）循環，與富堿（ na和k ）巖漿水混合，形成富堿中高溫高鹽度流體。The comparison study of the three belts indicates although they are distinct from each other all the three belts show many common features in the aspect of the metallogeny of large - rich vein uranium deposits, i. e : the important metallogenic areas are located above the old crystalline basement ; the paleo - rifting ( taphrogeny ) controls the development of the volcanic belt and at the same time it is favourable metallogenic tectonic environment ; the occurrence of uranium deposit does not depend on the lithology of volcanic rocks ; uranium metallogeny is obviously constrained by deep geologic processes and the connected fault - structural net is the necessary condition for the formation of large - rich uranium deposits
對比研究表明，雖然它們各具特色，就脈型富大鈾礦床成礦作用而言，它們又具有較多的共性：重要成礦區的火山噴發皆奠基在古老的結晶基底上；古裂谷（或裂陷）既控制了火山巖帶的發育，又是有利的成礦構造背景；鈾礦賦存對火山巖的巖性沒有明顯的選擇性；鈾成礦的深部控製作用明顯；聯通的構造網路系統是形成富大鈾礦的必要條件。There is a close relation between mesozoic tectonic evolution, fluid evolution, petrogenesis and mineralization in the manzhouli - e ' erguna region in the northeast of the northern orogenic belt, china, and three evolution stages of the mesozoic tectonic - fluid - petrogenetic and metallogenetic system are proposed out : 1 ) acompanied by ree and cu mineralization, the calc - alkaline volcanic rocks and mantle - crust mixed type granite occurred under the regional tension tectonic background caused by the mongolia - okhotsk residual ocean that was closing in scissors form in the early - middle jurassic. 2 ) acompanied by pb, zn and ag mineralization, the calc - alkaline and alkaline volcanic rocks occurred under the regional shear - compression tectonic background in the late jurassic. 3 ) acompanied by u, f, pb, zn and ag mineralization, the caic - alkaline and alkaline volcanic rocks occurred under the regional tension tectonic background in the early cretaceous
摘要本文討論了北方造山帶東北段滿洲里額爾古納地區及其毗鄰區中生代構造流體成巖成礦系統及其演化的三個不同階段： 1 ）早中侏羅世張性「似裂谷環境」下所形成的中基性堿性火山巖、同熔性花崗巖及深源流體活動形成的稀土礦床和斑巖性銅鋁礦床； 2 ）晚侏羅世擠壓剪切環境下所形成的酸性火山巖、斑巖類及深源流體活動所形成的鉛鋅銀礦床； 3 ）早白堊世張性環境下所形成的基性堿性火山巖及深源流體活動所形成的鈾礦床、金銀礦床及螢石礦床。Deep & thick soft clay formed from sea facies sediment extensively distributing near the littoral in southeast china, due to its low shear strength and high compressibility, results in many difficulties in design & construction of groundwork. especially, post - construction settlement control problem has been to be solved desirably
我國東南沿海地區廣泛分佈著海相沉積的深厚軟土，由於深厚軟土的強度低、變形大，給地基基礎工程的設計與施工帶來許多困難；特別是近年來一些大型工程的工后沉降問題，正日益成為巖土工程領域亟待解決的重要課題。分享友人
