近共結巖
英文
anchieutectic rock-
Principal compresso stress of mineralization epoch is measured 34 - 46ma by means of ae method, and its orientation is ew - trending by conjugate fracture, at last, the dynamic mechanics of the rhombic shear fault grid is analysised, ore - controlling law of the regional and ore - belt are determined, and combined with geophysical prospecting, ore - forming are forec ast
利用巖石聲發射測得成礦期主壓應力值為34 - 46mpa ，以共軛破裂求得主壓應力方位為近ew向，分析了本區菱形剪切斷裂網格控礦構造應力場的動力學機制。提出區域和礦帶的成礦控礦規律，結合物探進行了成礦預測。When there is original stage support only, the load ratio of surrounding rock gets more and more bigger with the increasing of crust stress, correspondingly, the load ratio of initial stage support gets smaller. when the initial stage support and the second support act each other, the load ratio of surrounding rock is more than fifty percent, and it has little change with the increasing of crust stress. the whole analysis of the surrounding rock and support shows that the bottom arch of liner and the feet of liner have serious stress concentration, so do the sidewalls and the foot of a wall of the surrounding rock
通過屈曲理論分析結果對比表明，彈性屈曲和突變失穩分析的結果比非線性屈曲分析的結果要大得多，非線性分析由於考慮了材料非線性和幾何非線性，因而結果與實際接近實際；當只有初期支護時，隨著地應力的增加，圍巖的荷載分擔率增大，相應地，初期支護的荷載分擔率就減小了；當有初期支護和二次襯砌共同作用時，圍巖的荷載分擔率在50以上，這一分擔率隨地應力的增加其變化不大；支護和巖體的整體分析表明，襯砌底拱及拱腳處應力集中嚴重，隧道巖體側墻及墻角圍巖的應力集中也較大。" the effectiveness of artificial reefs, as a resource enhancement device, has been clearly demonstrated by the deployment of artificial reefs in three marine parks in hong kong in the past few years. bio - diversity and abundance of commercial fishes found around the artificial reefs are much higher than those observed in nearby natural rocky shore areas
過去數年，漁護署在三個海岸公園敷設人工魚礁，結果清楚顯示人工魚礁在增加漁業資源方面的成效。人工魚礁四周的生物多樣性及有商業價值魚類的數量，均比在附近的天然巖岸區所見的高許多，至今在人工魚礁共錄得超過一百三十五個魚類品種。
