藕塘地区线路工程铁塔基础型式技术经济对比分析

Comparative Analysis of Basic Technical and Economic Types of Railway Engineering Towers in Qiangtang Area

对于铁塔基础处于鱼塘藕塘等特殊地质时,选用何种基础型式直接关系工程的整体造价。本文以北京通州地区大杜社110kV送电工程为例,选用了平板基础和灌注桩基础两种方案进行了技术经济对比分析。综合考虑藕塘属地质情况因素,比较两种方案,推荐采用平板基础方案较灌注桩基础方案,施工简单方便,经济效果明显。

When the foundation of the tower is in special geology such as fish ponds and ponds,what kind of foundation type is used directly relates to the overall cost of the project.Taking the 110 kV power transmission project of Dadushe in Tongzhou District of Beijing as an example,the paper selected two schemes of flat foundation and cast-in-place foundation to carry out technical and economic comparison analysis.Considering the geological conditions of Qiangtang,the two schemes are compared.It is recommended to adopt the flat foundation scheme compared with the grouting pile foundation scheme.The construction is simple and convenient,and the economic effect is obvious.
