摘要
广州地铁1号线车辆段为大面积软土地基,淤泥或淤泥质软土深度从0.5～9.4m,接触网基础设计成为一个难题。验证了人工挖孔桩填砂混凝土圆柱卡盘式基础和钢柱T形基础能够满足接触网供货商提出的标准和要求。试验方法有推广应用价值。
The ground of Guangzhou Metro Line 1 Depot covers a large area of soft soil. The average depth of mud or muddy soft soil is about 0.5 ~ 9.4 m, which makes the design of OCS's(Overhead Catenary System) basis very difficult. With an introduction to the site experiments in Guangzhou Metro Line 1 Depot, the author argues that two kinds of OCS' s basis, namely concrete pole chuck type basis and steel pole T - type basis shall satisfy the requirement of the OCS provider and the related standards, and therefore be worthy of adopting in other projects.
