Application of two - direction rectification of deviation by jack - up for dangerous inclining building with foundation subsidence 地基下沉傾斜危樓雙向頂升糾偏實(shí)踐
Speech by scit , mr john tsang at the roof jack - up ceremony of asiaworld - expo : english only 工商及科技局局長(zhǎng)曾俊華在如何在中國(guó)有效保護(hù)商標(biāo)品牌研討會(huì)上的致辭全文:只有中文
The differences lie in the different time of getting - up , different degree , level , scale , speed , jack - up potential and other regional imbalances and finally 最后,系統(tǒng)總結(jié)了本文的研究成果,并對(duì)未來(lái)的研究?jī)?nèi)容進(jìn)行了展望。
It is mainly used to carry out the underwater reef drilling and blowup in channels and harbors etc . this vessel can be self - jacked - up and down by its own four legs 32 . 00m本船為鋼質(zhì)全焊接結(jié)構(gòu)的沿海非自航箱型駁船,主要作用于航道港口等水下礁石鉆孔爆破。
The calculation results show that the jack - up platform under dynamic ice loads is in safe condition and can perform drilling operation in winter ice zone 計(jì)算結(jié)果表明,該平臺(tái)的樁腿在冰激動(dòng)載荷下的強(qiáng)度滿足安全要求,冬季繼續(xù)在冰區(qū)海域進(jìn)行鉆井作業(yè)是可行的。
The digital model for interactive action between ice and jack - up platform was established using ansys software , and the dynamic analysis of jack - up platform was performed 摘要為了保證自升式平臺(tái)冬季在冰區(qū)海域安全作業(yè),應(yīng)對(duì)樁腿結(jié)構(gòu)在動(dòng)冰載作用下的強(qiáng)度進(jìn)行評(píng)估。
The strength of legs of a jack - up drilling platform serviced in bohai sea is evaluated and the ice - induced fatigue damage of the platform leg under different ice parameter was determined 對(duì)渤海某自升式鉆井平臺(tái)樁腿進(jìn)行了強(qiáng)度校核,計(jì)算出不同海冰參數(shù)下平臺(tái)樁腿的冰激疲勞損傷。
The coupling effects of interaction between ice and platform structure are computed by taking a jack - up platform as an example , which will provide referential basis for the safety assessment of ice - induced vibration of jack - up platform 以某自升式平臺(tái)為例,計(jì)算了冰和平臺(tái)結(jié)構(gòu)相互作用的耦合效應(yīng),為自升式平臺(tái)冰激振動(dòng)安全評(píng)估提供了參考依據(jù)。
