500kV香山变电站地基处理研究

Research on Foundation Treatment at 500kV Xiangshan Substations

500kV香山变电站是在珠江三角洲深厚淤泥地质低洼地区建设的一座重要的枢纽变电站,本文通过对深厚淤泥地区的地质情况分析,结合本工程实际情况,指出变电站的不均匀沉降等地基破坏现象的成因,列举解决这一问题的多种方法。并根据分析研究比较,提出最佳的综合处理解决方案。该方案经过本工程的实践,取得了成功,达到预期的效果,取得了良好的社会效益和经济效益,为解决这一问题提供了有效的手段。

The 500kV Xiangshan substaition is an important hinge of substaition which is built in the low-lying area where the geologic condition is profundity silt in ZhuJiang Delta. According to the analysis of the geologic conditions in the area and based on the project, the cause for ground base damages, such as differential subsidence, is indicated in this paper. And various methods are listed to solve this kind of problems. The comparison has been made to put forward a best ground treatment solution. The solution was carried out successfully at the project and the expectable effect was gained. Social and economic effects have been achieved. An effective method has been presented to solve these problems.
