摘 要: | 在日本学者提出的约束矩阵法的基础上,提出了用来计算碾压混凝土坝温度应力的广义约束矩阵法,该方法可同时进行几种计算方案比较,为复杂成层结构的应力分析提供了一条简便的技术路径;并可计算出允许温度场的分布情况,为温控设计提供依据。

Generalized constraint matrix method for calculation of temperature stresses |
| |
Abstract: | Based on the constraint matrix method developed by Japanese scholars, a generalized constraint matrix method was proposed for calculation of the temperature stress of RCCDs. By the method, several calculation alternatives were compared, providing a convenient measure for analysis of temperature stresses of multiple layer structures. Furthermore, the method could give the distribution of permissible temperature fields, providing a basis for temperature control design. |
