发布时间：2018-11-20 07:17
【摘要】：随着我国水电事业的进一步开发,越来越多的水电站位于我国西部高原高山地区,其开发条件也越来越艰难。水电站调压井作为水电站的一个重要组成部分,由于其荷载与边界的多样性、复杂性且埋于岩体中,属于地下结构工程的范围,目前调压井结构分析的主要手段是荷载结构法和地层结构法。本文以国内某水电站调压井为例,运用结构力学法和有限差分软件FLAC3D对水电站调压井进行结构分析。 本文所作工作主要如下： 1、利用结构力学法对该调压井进行结构计算,分析其井筒与底板的受力情况。 2、运用有限差分软件FLAC3D对调压井所在区域进行应力分析,并对其结构在不同工况条件下进行计算分析。 3、通过对两种计算方法的结果分析,得到两种计算方法的规律性及差异性。 4、提出一些建议和意见,为以后的工程设计及科学研究提供一些参考。
[Abstract]:With the further development of hydropower industry in China, more and more hydropower stations are located in the highland and alpine areas of western China, and the development conditions are becoming more and more difficult. As an important part of hydropower station, the surge well of hydropower station belongs to the scope of underground structure engineering because of its diversity of load and boundary, complexity and buried in rock mass. At present, load structure method and formation structure method are the main means of structure analysis. Taking a hydraulic well of a hydropower station in China as an example, the structural analysis of the well is carried out by means of structural mechanics method and finite difference software FLAC3D. The main work of this paper is as follows: 1. The structure of the well is calculated by structural mechanics method, and the stress on the shaft and bottom plate is analyzed. 2. The finite difference software FLAC3D is used to analyze the stress of the region where the pressure well is located, and the structure of the well is calculated and analyzed under different working conditions. 3. By analyzing the results of the two methods, the regularity and difference of the two methods are obtained. Finally, some suggestions and suggestions are put forward to provide some references for future engineering design and scientific research.
