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。
