抗拔桩和压顶梁对明挖地铁车站内力影响分析
Analysis of the Impact of Uplift Pile and Coping Beam on Internal Force of Metro Stations Constructed by Open-and-cover
摘要
Abstract
There often exists anti-floating problem in the construction of the subway station in high water table areas. The handling of anti-floating is directly related to the reliability of subway station during normal operation of the subway station. Handling anti-floating with different measures may have different effects on the internal forces of the structure. To study the effects and seek some suggestions in the light of structural stresses, this paper, with reference to a metro station constructed with cut-and-cover method and on the basis of the two most common anti-floating measures — capping beam and uplift pile in the numerical calculation, concludes that the uplift pile can improve the effect of the structural stress, when the span of the structure is large, the uplift pile alone or the combination of uplift pile and capping beam shall be employed to fulfill anti-floating;if the span is small, capping beam shall be prioritized.关键词
