Abstract : according to the site condition of the bisc , a mathematical model of two - dimensional unsteady solidification and heat transfer was established for the bloom caster in the mold . the mathematical model was solved with a finite difference method to characterize the temperature profiles and thickness of the solidified shell in the mold , the effects of casting speed on thickness of the solidified shell are also studied 文摘:根据包钢的现场条件,建立了大方坯连铸机结晶器内二维非稳态凝固传热数学模型,采用有限差分法对数学模型求解,得出结晶器中铸坯的温度分布规律和凝固坯壳生成规律,同时研究了拉坯速度对坯壳生成厚度的影响
6 before commencement of works , the permit holder shall conduct a site assessment on land contamination in accordance with the environmental protection department practice note for professional persons ( propecc ) pn 3 / 94 to establish the site condition before construction and operation of the temporary bus depot 在展开工程之前,许可证持有人须按照环境保护署发出的《专业人士环保事务谘询委员会专业守则3 / 94 》进行土地污染评估以确定在建造及营运临时巴士车厂之前土地的情况。
The geological condition and hydrogeologic condition is the key factor to slope stability , the deformation damage mechanism and mode of slope . however , the geological condition and hydrogeologic condition are always different as the site varies , so there is almost no slope which can totally copy the experiences from the other slopes . as a result , it is necessary to study the site condition in order to analyze the stability with different specific site 由于边坡的地质条件和水文地质条件是边坡稳定性的控制性因素,决定了边坡的变形破坏机理和类型,而地质条件又是千差万别的,因此,没有哪一个边坡可以完全套用已有的经验,这就决定了边坡研究具有典型的场地特征,必须具体问题具体分析。
Furthermore , the construction management of the fabrication and erection of the box beam is in complexity for the new workmanship , various procedures , and very special site conditions which should be taken into account so as to achieve the construction objectives in terms of safety , quality , progress respectively . with the various external affections , the working period was extremely tight for fabrication and erection of the box beam by the sixth company limited of fifth china railway group on the qinshen special passenger line , consequently , progress management became the 因诸多外界原因的影响,中铁五局六公司在秦沈客运专线进行制梁和架梁施工中都遇到异常紧张的工期要求,施工进度管理成为其施工管理的关键,文中重点介绍的网络法组织箱梁制造施工和结合现场实际、分析施工工序、测定作业效率来控制架梁进度的方法对箱梁的制造与架设施工是极为有效的、科学的管理方法,对施工项目的各项管理都有借鉴意义。
Influencing factors of buried pipeline ’ s damage and numerical modeling are investigated . complex site conditions , fault and fluid - pipe coupling are considered . considering soil - pipe interaction , boolean operator is used to merge site and pipe , and site - pipe physics contact is solved through soil - pipe friction 考虑到场地和管道间的相互作用,在adina三维有限元建模过程中,应用布尔操作实现场地与管道间的几何融合,并通过管土摩擦解决场地与管道间的物理接触问题。
The study results of influences of site condition on ground motion are examined and some problems needed are pointed out . using the numerical method for seismic response analysis , the seismic responses of different site models under all possible combinations of seismic input from the base are calculated 在此基础上,结合大量的工程场地模型,利用场地地震反应分析的数值计算方法,计算了不同场地模型及基底地震动输入组合下的场地地震反应,定性定量地分析了这些分类场地上的地震反应的特点及规律。
The deformation analysis was made to a 12 storey reinforcement concrete structure , building in site condition ii , earthquake fortification level 8 , by a program idarc - 2d which is put forward by the state university of new york at buffalo . the strong ground motion records obtained from pacific earthquake engineering research ( peer ) stiong ground motion database . thirty - eight waves were selected from the database by sorting the site condition and peak ground acceleration a comparison was made to the thirty - eight records " response spectra and the design response spectrum . thirteen waves were selected to the deformation analysis , el - centro wave and taft wave were added as a comparison . the result of computation shows that the selected waves damaged the structure severely than the el - centro wave and taft wave 利用idarc - 2d对一建于8度类场地上的12层钢筋混凝土框架结构进行了大震下的变形验算。强震记录取自加州国家地震中心强震数据库,按场地类别和峰值加速度对数据进行分类处理,从中选出38条波进行反应谱的拟合。最终选定拟合较好的13条波进行本次试算,作为比较加入了常用的el - centro波和taft波。
