In the Construction of large concrete dams, a considerable amount of heat is generated when concrete sets. This heat induces serious thermal stress in the concrete blocks. In the usual engineering practice, the period between successive pouring of concrete is prolonged to allow the transference of heat into the atmosphere.

In the Construction of large concrete dams, a considerable amount of heat is generated when concrete sets. This heat induces serious thermal stress in the concrete blocks. In the usual engineering practice, the period between successive pouring of concrete is prolonged to allow the transference of heat into the atmosphere. For large dams, this is in conflict with the rapidity, of construction. In order to resolve this difficulty effectively, we have to find means to calculate the thermal stress.The calculation of thermal stress involves calculating the field of temperature distribution, field of elastic stress and creep stress. Being considered as a plane problem, the temperature T(x,y,t) satisfies the following equations (refer to fig. denotes derivatives along the outward normal.a, λ, α are constants.θ(t)is the temperature rise of concrete under adiabetic condition. The stress induced by the fields of temperature distribution and gravity has a stress function Ψp(x,y,t) satisfying the following equation:Δ2Ψ = Eldl/1v2ΔT = 0 in region Gl (1=0,1) The boundary conditions are :along CBAA'B'C' normal stress and shearing stress being zero.along CDD'C' displacement being zero.on surface L0, normal stress σy, shearing stress τxy and displacements u,v satisfy continuity conditionThis paper gives a preliminary treatment to the calculation of the two problems stated above. Several theoretical questions involved in the calculation will be further investigated in the near future.

在混凝土大坝的浇筑过程中,混疑土硬化时所放出的大量热量,会在浇筑块内引起严重的温度应力。为了降低坝内的温度应力,一般工程中采取了降低施工速度的办法,使坝内热量有机会向大气发散,但在大坝工程中,它却与施工速度产生了巨大矛盾,要有效地解决这一矛盾必须首先解决温度应力的计算问题。 温度应力的计算包括了温度(?)、时弹性应力(?)及徐变应力的计算。作为平面问题处理,温度T(x,y,t)满足 其中;表外法向微商α、λ、α皆为常数,θ(t)为混凝土在绝热状态下的上升温度。 由温度应力场和重力场的作用所产生的应力,其应力函数ψ(x,y,t)满足 Δ~2ψ+E_lα_l/(1-v_l~2)ΔT=0 在G_l内(l=0,1)边界条件为: 沿CBAA′B′C′,正应力及剪应力为零; 沿CDD′C′,变位为零: 在接触面L_o上,正应力σ_y,剪应力τ_(xy),位移u、v满足连续条件。 本文仅就以上二问题的计算作了初步研究,计算中所牵涉到的一些理论问题,尚待今后进一步研究。

The rheological properties of various Coal-Oil slurry and Coal-Water slurry prepared by Pindinsan bituminous coal powder with Daqing heavy oil and water under the conditions of the coal powder concentration 0-69% by wt and the temperature ranging from 14℃to 120℃ have been studied experimentally. The fields of temperature and velocity at various sections along axis of tube are obtained by numerical solution from the momentum and energy equations. The drag coefficient and heat transfer coefficient of COM as it is flowing through the pipe and is heated up around the entire pipe while keeping pipe wall temperature at constant are calculated. The results are compared with 165 sets of resistance data and 408 groups of heat transfer data determined experimentally.

文献[1]研究了在有稳定换热过程的管道流动中.当粘性系数μ是温度的指数函数时,在甚么条件下发生一维非等温流动.对于平面渠道及圆管的流动,还研究了速度及温度场.本文对同样问题补充提出了二种新的解法.文献[1]的方法可看成是本文方法的一个自然的分支.两个新解法中的一个只能求解文献[1]的同样问题,其计算过程的复杂程度也和文献[1]不相上下;但是另一个却能超出文献[1]的研究范围,即对管道的横截面的周界不是等曲率曲线的情形亦可求解.
