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.

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.

Wind load is one of the major loads in structural design. Its value is a function of wind pressure. The basic wind pressure given by the Load Code of China should be determined by the probability distribution of the maximum basic wind pressure which may appear in 50 years. In fact, it is very difficult to get the probability distribution directly. Usually, it can be deduced from the distribution of year's basic wind pressure.Based on the historical data, it has been verified that both of the distribution of...

Wind load is one of the major loads in structural design. Its value is a function of wind pressure. The basic wind pressure given by the Load Code of China should be determined by the probability distribution of the maximum basic wind pressure which may appear in 50 years. In fact, it is very difficult to get the probability distribution directly. Usually, it can be deduced from the distribution of year's basic wind pressure.Based on the historical data, it has been verified that both of the distribution of year's basic wind pressure in China and the distribution of month's basic wind pressure in Beijing can be described as the extreme-type Ⅰ distribution. It is also verified that the distribution of standard period basic wind pressure can be deduced from the distribution of month's basic wind pressure and has the distribution of the extreme-type Ⅰ too.Mathematical expectation of standard period wind distribution is art important parameter, because in the current Load Code of China, basically the standard values of basic wind pressure equal the mathematical expectations of designed standard period wind distribution after taking into consideration a factor of wind direction. In this paper, the mathematical expectations of basic wind pressure distributions deduced from theory corresponding to eight different standard periods are obtained. Meanwhile, the comparison between the mathematical expectations and the averages of practical recorded data is made. The results of analysis indicate that the accuracies of estimated averages of wind velocities are quite high.In addition, a unified parameter and a coefficient of effect of wind direction are suggested.

风荷载是结构设计中的主要荷载之一。它的值是风压的函数。我国荷载规范中的基本风压规定应由五十年内可能出现的最大基本风压的概率分布来确定。实际上,这种概率分布很难直接求得。通常,它可按年基本风压的分布推出。利用历史数据,可以证明我国的年基本风压和北京地区的月基本风压的分布都可描述成极值——Ⅰ型分布。同时可以证明基准期的风压可以用月风分布推求,且可描述成极值——Ⅰ型分布。基准期风分布的数学期望是一个重要的参数,我国现行荷载规范中基本风压的标准值,就是考虑了风向因素后的设计基准期风压分布的数学期望。本文列出了八种不同基准期的风压分布理论上的数学期望。同时将数学期望与实际记录数据的平均值作了对比。分析结果表明,估计的风速平均值的精度相当高。
