【摘要】 在基坑围护结构设计中,等值梁法是计算围护结构内力的经典方法。以某基坑工程为例,运用等值梁法进行单支点排桩围护结构设计,分析了采用不同方法确定土压力零点位置的差异及土压力零点位置对桩身位移与内力的影响。最后,根据分析结果,提出了合理确定土压力零点位置的几点建议,供设计参考。更多还原

【Abstract】 In the supporting structure design of foundation pit,the equivalent beam method is one of the classic methods of calculating the internal force of support structure.With a foundation pit project as an example,the single point row piles support structure was designed and calculated with the equivalent beam method.The differences of the position of earth pressure zero point by using different methods and the influence of the position of earth pressure zero point on the displacement and internal force of piles were analysed.Finally,according to the analysis results of this paper,some suggestions were proposed about determining reasonably the position of earth pressure zero point for designing reference.更多还原
