The elastic stress diagram design method is behind the times and cant meet the command in practice.In the paper the author collected and analyzed a large amount of data about the SLRCP on several typical domestic model experiments and the projects in practice. By summarizing and analyzing the data, the author set up a typical computing model and analyzed the model by the software ANSYS, by reading the output data of the stress and the crack from the program, combined with the experimental results, the author summarized the destroy procession of the stock. The paper also discussed the influence of other main factors to the crack and the stress besides the internal water pressure, such as the concrete material, the dimension of stock and the way of laid-out steel bars.

本文通过对大量实际工程中的坝后背管资料的收集、归纳和分析，选取了具有代表性的计算模型；用有限元软件ANSYS计算了典型坝后背管结构在实际内水压力作用下的应力分布和裂缝发展情况；以国内几个有代表性的模型试验和有限元计算的成果为依据，分析了在内水压力作用下钢衬钢筋混凝土压力管道管壁裂缝的特点，并尝试总结出此种管道的裂缝出现的原因及其发展规律，同时确定了坝后背管结构极限状态的新的定义方式——以坝后背管的裂缝宽度来定义。

Through referring related documents and analysis of builded bridges home and abroad, this dissertation makes anslysis on design of whole bridge on the basis of design theory for general box-girder, and combined with the design of Long-March bridge. There makes a special research on shear connecter which connecte corrugated steel webs with concrete board up and down. Design method of shear connecter is discussed.

Time are tested under different kinds of stress for nitrided and un-nitrided specimens made from 35CrMo steel. The testing time ranges from 70 to 80 hours. The following equations are regressed from the tested curves: Un-nitrided specimens:〓 Nitrided specimens:〓 The above equations are consistent with the first stage theory for creep.

为此本文通过实验，测试了35CrMo钢渗氮和未渗氮两种试样在500℃时不同应力情况下的应变随时间的变化曲线，实验时间为70-80小时，将测得的曲线回归出以下方程：未渗氮样品：〓渗氮样品：〓以上方程符合蠕变的第一阶段陈化理论公式。

Through examining and analyzing of the crack in corbel of bridge of Dangtu road in Hefei, a strengthening scheme to paste the steel plate is put forward. The theory of non-linear finite is adopted to analyze the scheme with three dimensional finite element. The result of stress at the crack point which has been reinforced is also made clear.

The only alternative and referential way to predict the phase transformation temperature is to make use of the continuous cooling transformation diagrams, which are measured dilatometer curves that have not taken the effect of practical welding conditions into account.

由于焊接过程的瞬时性和焊接热影响区温度场、应力场的复杂性，该区域的组织转变往往并不完全遵守热处理条件下CCT 图所反映出的相变规律，因此为了提高焊接接头的性能，有必要深入研究真实焊接条件下热影响区组织的相变规律，尤其是马氏体组织的相变规律，因为在含碳量较高或合金元素较多的情况下，这两类钢的淬透性较强，在焊接热影响区极易形成高硬度马氏体组织，从而严重影响焊接接头的性能。
