Analysis on distribution features of gas outburst from two walls of normal fault and geological origin 正斷層兩盤(pán)的瓦斯突出分布特征及其地質(zhì)成因淺析
The fault faults from basemet to quaternary system , and has the feature of contemporaneous and normal fault 該斷裂自基底一直斷到第四系,具同生正斷特征。
The focal mechanism is mainly left - lateral strike - slip , with a very small normal fault slip component 這次地震的震源機(jī)制基本上是左旋走滑,帶有微小的正斷層滑動(dòng)分量。
The extensional and transtentional structure existed in huabei belongs to vent fault , fracture is mainly stepwise normal fault , whose preservation condition is not good 華北地區(qū)多為張性,張扭性構(gòu)造,屬于排氣斷層,形成的斷裂多為階梯狀,以正斷層為主,保存條件欠佳。
Several normal faults within the hainan fault zone constitute a fault - step zone and form a narrow and steep zone , which controlled the development and distribution of depositional systems in this area 研究認(rèn)為,海南斷裂帶的幾個(gè)北掉斷層構(gòu)成斷階帶,形成湖盆邊緣陡且窄的地貌特點(diǎn),控制了該區(qū)沉積體系的展布規(guī)律。
According to the relative membership degree of normal fault mode to needing checking mode , fuzzy optimum selecting theory is application to transformer fault diagnosis . it may judge fault more explicit than fuzzy even weight model 本文提出的模糊優(yōu)選法進(jìn)行變壓器故障診斷,是根據(jù)標(biāo)準(zhǔn)故障模式對(duì)待檢模式相似的相對(duì)隸屬度的大小來(lái)判斷故障,比模糊平均加權(quán)模型對(duì)故障的判別更為清晰。
The extensional activities of hefei basin occurred in the period between late cretaceous and paleogene . as a result , the extensional normal faults were took place along the pre - existing nearly ew faults and the tan - lu fault zone . the deposition of half - graben was formed 合肥盆地的伸展活動(dòng)發(fā)生于晚白堊世至早第三紀(jì),伸展活動(dòng)是疊加在前兩期走滑構(gòu)造之上,形成了以半地塹式楔形為主的沉積。
The thesis sets up a diagnose knowledge base , which considers the normal fault of hydroelectric unit and the characteristics of the no . 3 unit of guizhou dongfeng hydropower plant . with this condition , the system can diagnose the elementary fault of the unit to assist in operation and servicing 同時(shí)針對(duì)水輪發(fā)電機(jī)組的一般故障及東風(fēng)水力發(fā)電廠3 #機(jī)組的特性,總結(jié)了一套故障診斷數(shù)據(jù)庫(kù),在此基礎(chǔ)上對(duì)機(jī)組進(jìn)行初步的故障診斷以輔助電廠進(jìn)行檢修決策
2 . tazhong ancient uplift originated from normal fault in paleozoic , hydrocarbon formed in ordovician period , structure reverse made tazhong uplift form from the middle ordovician period to the late ordovician period , and it provided geologic background for the deposit of silurian - devonian stratum . tazhong uplift formed at the end devonian , ancient reservoir was destroyed and asphaltum sandstone formed , structure deformation more destroyed ancient reservoir in early permian , after then the major of structure deformation is regulation 塔中隆起源于早古生代拉張背景下的正斷層,寒武-奧陶紀(jì)為其烴源巖形成的重要時(shí)期;早奧陶世末-晚奧陶世末的構(gòu)造反轉(zhuǎn)是塔中隆起的主要形成期,同時(shí)也為志留系形成地層及復(fù)合圈閉提供了古地理背景;志留?泥盆紀(jì)塔里木盆地南北緣均轉(zhuǎn)為活動(dòng)大陸邊緣,形成了大量的斷裂和不整合;泥盆紀(jì)末塔中鼻狀隆起基本定型,古油藏遭受破壞,形成了瀝青砂巖;早二疊世晚期的構(gòu)造變形使古油藏遭受進(jìn)一步的破壞;二疊紀(jì)后構(gòu)造變動(dòng)主要以調(diào)節(jié)為主。
Analyzing the propagation behaviors for open and close crack , the author gain that normal fault is more dangerous to earthquake than reverse fault and glide fault . 3 . appling fracture mechanics to discuss reservoir - induce earthquake mechanism , the author observes the characteristic of surface crack and gains the stress intensity factor induced by the pressure of rock , water and osmosis 針對(duì)庫(kù)區(qū)斷層為表面裂紋這一特點(diǎn),研究水庫(kù)地震的斷裂特點(diǎn),得出地應(yīng)力作用下的應(yīng)力強(qiáng)度因子、庫(kù)水作用下的應(yīng)力強(qiáng)度因子和滲壓作用下的應(yīng)力強(qiáng)度因子以及它們的應(yīng)力強(qiáng)度因子之合,并且合理的解釋了構(gòu)造型水庫(kù)地震的誘發(fā)機(jī)理。
