By the preetressed anchorage test on prestressed concrete pier used for a 1 : 1 seale mOdlingpodeetal in Ankang Hydropower station, the stressing value Pd and the average stressing value P of asinglesteel line in the anchor lines are determined. The ration of Pd to P is defined as the stressing uniformity coefficient of one steel line. Through com prehensive analysis of test data, the variation of P(reading of preaure metre on tensile jack)with the uniformity coefficient can be deseribed by thefunctional relations, The stressing uniformity of a single steel line on work conditions during tension anchoring can be directly analysed from the relative regression curves presented in thispaper.

本文通过在安康水电站工程预应力混凝土闸墩1:1模拟试验台座上的预锚试验,同时测出了锚索中单根钢绞线受力值Pd和整束锚索的单根钢绞线平均受力值,并定义Pd与的比值为锚索中单根钢绞线受力均匀性系数。经对试验数据进行整理、分类组合及综合分析,找出了锚索的张拉力P(张拉千斤顶上压力表读值)与均匀性系数的=A·PB函数关系,再进行回归分析,从显著相关的回归曲线上,可直观地得出单根钢绞线在锚索张拉锚固时各种工况下不同位置上受力的均匀性。

The FEM-BEM coupled method has been used to analyse tall building-foundation-soil interaction taking material nonlinear properties into account. Quadratic curve isoparametric boundary elements model soil,eight-nodes isoparametric finite elements were used for concrete or reinforced concrete in beams and columns, bar elements with two nodes were used for steel reinforcements, quadrilateral link elements were used to model the bonding and slipping conditions between steel line and concrete in beams and columns. According to the conditions of displacement compatibility and force equilibrium on the interface, the FEM and the BEM were coupled. The results of calculation is satisfying. Compared with single FEM, it has the advantages of the covenient preparation of data and the high precision of calculation.

本文采用有限元—边界元耦合方法,对高层建筑与地基基础的联合作用进行了考虑材料非线性的分析.地基部分用二次曲线等参边界单元来模拟;上部结构中的混凝土及受拉主钢筋分别用八节点等参单元和二节点线形单元来模拟;而混凝土与钢筋之间的粘结—滑移关系则用四边形联结单元来模拟.根据两部分接触面上位移协调和力的平衡条件,将FEM和BFM进行耦合.用FORTRAN77语言编制了计算机程序,并在COMPAQ386/20e计算机上进行了实例计算.结果令人满意.该方法充分发挥了有限元在非线性分析中的优势和边界元在半无限域应用中的优势,较之单一的有限元法,具有数据准备简单,机时耗费量和内存需求量少,计算精度高的优点.

The paper describes the experiments concerning butt-welding of the X- 65 Grade seamless steel line pipes with different fluxes and under different welding conditions. Results of the said experiments show that X- 65 Grade line pipes jointed with the special butt-welding technique can be used for acid oil/gas transport. In case of underground service pipeline jointed by means of welding with cellulose electrodes can be free of the heat treatment to the weld, and pre-welding heating of the joint will ensure impact toughness of the weld. For overhead pipeline, welding with basic-compound coated electrodes and pre-welding heating of the joint will reduce the joint thermal -stress.

介绍了采用不同焊料和在不同焊接条件下进行的X-65钢级无缝管的对接焊试验。试验表明:采用特殊的接头焊接技术焊接的X-65钢级管线,可以输送酸性油、气;采用纤维素焊条焊接的地下管线,焊接头可不进行热处理;若焊前先将接头预热,可保证焊缝的冲击韧性;采用碱性药皮焊条和焊前接头预热的施焊方法,焊接的空间管道接头热应力小。
