Based on the previous research on the portal crane administration, one standpoint put forward in this paper is idea that is on the foundation of reliability in this paper, two viewpoints take shape when reason is analyzed, that is fatigue break and appearing the flaw that will extend. What is the fatigue break?(this phenomenon is always happen in some place),the fatigue is that board appears apophysis and concave when the board is pressed .so that the board ability of bearing the weight of load will descend. Second , the board appear the flaw that the flaw extends in the some place of board one reason is that the machine works too long, so the board ability of bearing the weight of load will decline.

本论文建立在已有的港口装卸机械管理的研究基础之上，进一步提出了以可靠性为基础的港口装卸机械的管理思想，已有的研究表明，港口机械设备破坏主要由于两个原因，第一是稳定性问题，特别是构件的局部稳定性，所谓稳定性是指：在板的平面内，板受到平行于板面的压力作用，使板发生隆起、内陷等凹凸不平的结果，从而使板受载能力减弱；第二是结构出现疲劳裂纹及其扩展，这是由于设备长时期运行，而造成设备某些部位出现裂纹并得以扩展，使设备承载能力下降。

针对上述各种计算理论及分析内容，自行编制了相应的面向对象计算程序PIASRFS-2007，程序用C++语言在VC++平台中编制，采用该程序可以采用无网格法对筏板基础进行计算分析，并能对不同平面形状、不同厚度的筏板基础与Winkler、双参数弹性地基及高层建筑的不同上部结构进行三者的共同作用计算分析，该程序为高层建筑筏板基础工程实践提供了一种新型有效的分析手段。

In this paper, several traditional models for computing are introduced at first. Conferring probability theory, the load boundary condition of that collector is analyzed, the characteristic values of Tubesheet in different design reference periods are computed. Based on homogenization method, after lots of numerical experiments, the mechanical characteristic of Tubesheet controlled different structure parameters is studied, and an empiristic formulas that could simplify Tubesheet to stiffen plate is gained. Then, G-M method is employed and Tubesheet is simplified to a normal plate.

Again, I maintain that we should use the flexural-tensile strain and the vertical shearing stress of the bottom of cover of the joint as the target for the design of the cover structure of asphalt on the old cement concrete. In addition, on the basis of much theoretical analysis, I preliminarily put forward to a designing methods to anchor the old cement concrete road by using dog irons made of iron bars and then covering it using asphalt concrete structure. Finally, through selecting the plan of the cover of the road to be experimented, and making a detailed introduction to the techniques of construction according to the result of theoretical analysis, I know that after anchoring the slabs close to each other with dog irons made of iron, and then cover them using asphalt cement concrete has an obvious effect on preventing and slowing down the reflection cracks in the bituminous concrete skin coat over the old road.
