The calculation of transverse load distribution of arch bridges as a method for analysing the space distribution of stresses in the arch is an urgent, practical and theoretical problem yet to be solved. This paper attempts to offer an approach to the subject. As an approximation, a circular arch bridge with hinged ends and constant cross-section carrying radial external loads distributed along the arch according to trigonometric function is considered, taking into account especially the particularity of the double-arched bridge (wave-form cross-sectional type ot arch bridge) which is popular in China. At first the chief loading forms, the stresses and deformations of a single arch are analysed. Thereupon the space distribution of the stresses and deformations in the arch system composed of single arches is calculated, yielding finally the required transverse load distribution of the axial force and bending moments of the arch bridge. This approach may be called a finite arch strip method. The treatment of the fixed end arch bridge, of the continuous arch bridge and of the superstructure on the arch is discussed and practical proposals are made for the solutions. The theoretical analysis shows that large longitudinal shears can be produced between the neighbouring arches, which may be the main cause of the tangential cracks in some existing arch bridges.

拱桥的荷载横向分布计算,作为拱桥内力空间分布的一种分析方法,是亟待解决的实践与理论问题。本文试图从理论上对此进行分析。近似地以常截面双铰元弧拱桥承受沿拱轴按元函数分布的径向外荷载作为分析对象,着重针对我国广泛采用的双曲拱桥。首先讨论单片拱的主要荷载形式,分析单片拱的受力和变形,进而组合、计算多片拱体系的空间受力和变形,由此求出各片拱的轴力和不同截面的弯矩的荷载横向分布规律。所用的方法可以说是以一整片拱为单元的有限元力法。对固端拱、多孔连续拱和拱上建筑的处理,作了讨论和实用的建议。这里的理论分析表明,在相邻拱片之间可能产生相当大的纵向剪力,它可能是在一些建成的曲双拱桥的小拱波顶上出现纵向裂缝的主要原因。

This paper is a summary of the experimental results on site during the years 1974—1975. The method of calculation and empirical constants of the hydro-pressure of concrete propoed in this paper have been adopted by the technical specification on the slipform, as approved by the National Construction Committee. In this paper, the following problems are discussed: a) the design of pressure box; b) the maximum hydro-pressure exerted by fresh concrete upon the slipform, and its attenuation curve during and soon after construction; c) the hardening process of fresh concrete inside the slipform; d) curves and empirical formulas proposed for calculating the hydro-pressure of fresh concrete upon slipforms.

For a hydraulic tunnel, water load is the main one. In the static calculation of such a tunnel, it is a common practice to treat the water load as a boundary force without consideration of the time factor of groundwater. This will result in considerable error in some cases. This paper proposes a method to take the water load as a field force and to make static calculation of the adjoining rock mass and lining of the tunnel by considering the time dependence of water load on excavating and lining of tunnel. Owing to geological tectonic action, the rock mass is a medium invariably containing fissures. The calculation by way of seepage field allows this feature to be considered, and a corresponding mathematical model is used accordingly, in the static calculation, the rock mass is assumed as being anisotropic elastic medium, and consideration is made of the effect of joints and fissures, as well as of the dependenee of water load on the relative periods of tunnel excavating, supporting and lining. A special computer program SJDI is prepared on the basis of the above principle. This program also has function of calculating stress and displacement fields at various periods of tunnel excavatipg and supporting under the actions of seepage field and initial stre ssfield.

水荷载是水工隧洞的主要荷载.在隧洞静力计算中,通常把水压力作为边界力处理,而且没有考虑水荷载作用的时间因素.这种计算方法在某些情况下将导致较大的误差。本文建议的方法是把水荷载作为场力来处理,考虑水荷载与隧洞开挖及衬砌相对时间关系进行隧洞围岩及衬砌的静力计算.由于地质构造作用,岩体是裂隙介质,渗流场的计算考虑了岩体的这一特点,采用了相应的数学模型.静力计算视岩体为各向异性弹性介质,并考虑了节理裂隙的影响以及隧洞开挖、支护和衬砌施工与水荷载作用的相互时间关系.按上述原则编制出隧洞计算专用程序SJDI.程序中还附有在初应力场及渗流场作用下,计算隧洞分层开挖、分期支护时各个时段应力场及位移的功能.
