On the basis of analyzing forces on the self-supported column,the superposition method in mechanics of material was used to calculate the steady deflection at top of the high column under both of weight and distributed wind pressure.

在对自支承式塔设备建立合理的力学模型并进行受力分析的基础上，采用材料力学中的叠加法，计算了高塔设备在均布风载荷、自重联合作用下的塔顶静挠度，提出对于自重和长细比均较大的高塔，塔体自重对塔顶挠度的影响不可忽视，并推导出了计算这种影响的表达式。

On the basis of analyzing forces on the self-supported column, the superposition method in mechanics of material was used to calculate the steady deflection at top of the high column under both of weight and distributed wind pressure. The results show that the effect of weight to top deflection of the heavy weight high column can not be ignored and a formulation is deduced to express this effect.

Reducing self-weight and improving toughness is always a subject that modifying the common concrete since it is come into being , the steel fiber reinforced concrete pathed the way for improving the toughness of it ,while the lightweight concrete solved the problem to the heavy dead weight.

混凝土自从问世以来，减轻自重、提高韧性一直是对其改性的课题，钢纤维混凝土为改善韧性开辟了道路，而轻骨料混凝土则解决了其自重大的问题。

Finally, through the instance of engineering, we can see that the steel dosage in steel honeycomb plank is smaller and the self-weight of the whole structure is lighter comparing with pyramided grid structure, and the steel dosage in portal strut with honeycomb laminated beam-column system is still smaller and the self-weight is still smaller comparing with steel I-beam,they will have a wide applied foreground.

最后，通过工程实例分析表明，在大跨度屋盖结构中，金属蜂窝板-杆空间结构体系比常规的四角锥网架结构具有用钢量低，结构整体自重轻等优点；在轻钢结构厂房中，采用金属蜂窝纯板片箱梁体系比一般H型钢结构用钢量更低，自重更轻，具有广泛的应用前景。

The calculation results show that the initial geostress field in dam zone is a medium to high stress field composed of tectonic stress and dead-weight stress.

计算结果表明，大岗山坝区初始地应力场是一个在浅部以构造应力为主、在深部以自重应力为主、由构造应力和自重应力联合组成的中等偏高的地应力场，研究结果为坝区边坡开挖及长期稳定性分析提供了重要依据。

The tectonic stress is prominent at shallow level and the dead-weight stress is prominent at deep level, which provides important reference basis for excavating simulation and long-term stability analysis of slope.

计算结果表明，大岗山坝区初始地应力场是一个在浅部以构造应力为主、在深部以自重应力为主、由构造应力和自重应力联合组成的中等偏高的地应力场，研究结果为坝区边坡开挖及长期稳定性分析提供了重要依据。

Down pull effects during settlement result in the loads acting on top of projecting conduit are larger than the self weight of the soil above the conduit. On the other hand, for ditch conduits, the pressures on them are smaller than the self weight of the soil above them.

埋管受力与结构及其两侧土体的刚度有很大关系，上埋式管道，其两侧覆土变形相对大于管顶覆土，沉降中产生向下的拖曳效应，致使管顶受到相对其上土体自重更大的荷载，而沟埋式管道则与此相反，管顶受荷小于其上土体自重。

In this paper, a simplified mathematical model for solving the dead load forming of hull saddle shaped steel plate is derived by the theory of elastic mechanics of shell.
