The substructure adopts heavy load conventional drive self - moving mode and power steering system , which causes the rig good performance of the moving and cross - country 底盘为重载常驱动自走底盘，采用动力转向系统，钻机的通过性、越野性好。
In this paper , the main problem to be solved is how three different substructures , subjected to seismic load , affect , restrict , couple one another 在地震荷载作用下，三种不同的结构如何相互影响，相互制约，相互耦合是本文需解决的主要问题。
It not only richens the analysis method of lpda , but also validates the validity of the substructure analyzing method of interconnect - net 所得结论不仅丰富了对数周期天线的分析思路和方法，而且进一步有力验证了互联网络子结构思想的正确性和有效性。
The seismic resistance of xiaowan arch dam , where the contraction joints are considered based on substructure theory , is analyzed 摘要应用动力非线性子结构理论，对设置伸缩横缝的小湾高拱坝实际工程结构抗震分析中的坝体横缝加抗震钢筋问题进行了研究。
At the end of this part , the paper studies how to automatically divide the general wall element into shell elements , according to the theory of substructure 在结构静力计算模块还研究了根据子结构原理实现的通用墙元自动细化成壳元的实现方法和过程。
Abstract : this paper introduces the structure , principle , manufacture and applying methods of the climbing equipment for the construction of extraordinary bridge substructures 文摘:本文介绍了某特大桥墩台砼施工爬升设备的构造、原理和制作及使用方法。
The substructure adopts heavy load 14 8 conventional drive self - moving mode and power steering system , which causes the rig good performance of the moving and cross - country 底盘为重载14 8常驱动自走底盘，采用动力转向系统，钻机的通过性、越野性好。
Basically , the method is developed according to sensitivity analysis . the unit volume energy criterion of weak substructures of a structure system is proposed 在本文中提出了基于单元格能量的分析方法,这种方法基于灵敏度方法,它提出了薄弱机构的能量标准
In present method , direct sensitivity calculation is neglected and modification is carried out with the physical parameters of identified weak substructures 在现有的分析方法中,直接的灵敏度计算方法忽略的了这一点而且结构优化采用识别物理参数识别的方法。
Furthermore , geometrical sizes of superstructures are easier to perform . 2 . the prefabrication of superstructure segments can be processed while the substructure is under construction ( 2 )施工速度快，工期短；上部结构节段预制可与下部结构施工同时进行。
