摘要:
瓜洲泵站工程面临地基地质条件差、轻粉质和重粉质砂壤土居多、地基渗透性强和易出现液化的问题，不宜作为工程天然地基持力层。对无桩基础的瓜洲泵站进行稳定分析，据此引入含钻孔灌注桩基础的瓜洲泵站工程设计方案，并对其进行了稳定分析，提出了钻孔灌注桩地基处理施工技术的注意事项。最后，利用三维空间有限元法，对校核洪水运行工况下的瓜洲泵站结构进行数值模拟计算，通过分析泵站结构的应力和变形，验证设计方案的有效性。研究成果有望为泵站工程的地基处理及安全性能分析提供价值性参考。
Abstract:
The Guazhou Pumping Station project faces problems such as poor geological conditions of the foundation, a majority of light and heavy sandy loam soils, strong permeability of the foundation, and susceptibility to liquefaction, making it unsuitable as a natural foundation bearing layer for the project. A stability analysis was conducted on the Guazhou Pumping Station without pile foundation, and based on this, a design scheme for the Guazhou pumping station project with drilled cast-in-place pile foundation was introduced. The stability analysis was conducted, and precautions for the construction technology of drilled cast-in-place pile foundation treatment were proposed. Finally, using the three-dimensional finite element method, numerical simulation calculations were carried out on the Guazhou pumping station structure under the verification of flood operation conditions. The effectiveness of the design scheme was verified by analyzing the stress and deformation of the pumping station structure. The research results are expected to provide valuable references for the foundation treatment and safety performance analysis of pump station engineering.
