混凝土温度、变形分布变化规律比较清楚，但直接反映大坝安全状态的应力认识不足。该数据集为本课题高混凝土坝应力场构建技术下的计算成果，该数据集分为两个部分，其中txt文件为应力计算结果，第一行为节点应力英文，第二行从左到右为节点号，x方向应力（0.01Mpa），y方向应力（0.01Mpa），z方向应力（0.01Mpa），xy面应力（0.01Mpa），yz面应力（0.01Mpa），zx面应力（0.01Mpa），第三行到最后一行都是第一行对应的数值。可视化部分为msh文件和res文件，需要下载gid，通过gid打开msh文件即可查看应力场计算结果。", "ds_source": "

The changes in temperature and deformation distribution of concrete are relatively clear, but there is insufficient understanding of the stress that directly reflects the safety status of the dam. This dataset is the calculation result of the stress field construction technology for high concrete dams in this project. The dataset is divided into two parts, where the txt file is the stress calculation result. The first line is the node stress in English, and the second line from left to right is the node number. The x-direction stress (0.01Mpa), y-direction stress (0.01Mpa), z-direction stress (0.01Mpa), xy plane stress (0.01Mpa), yz plane stress (0.01Mpa), zx plane stress (0.01Mpa), and the third line to the last line are the corresponding values of the first line. The visualization part consists of MSH files and RES files. You need to download GID and open the MSH file through GID to view the stress field calculation results.
