在布置相同抗拔桩数量的情况下,抗压抗浮工况会有各自对应的最佳布桩方式,而布桩时桩与柱荷载作用点之间的距离是影响布桩效果的重要因素。为直观研究抗拔桩与柱荷载距离对地基梁内力的影响,本文结合某工程实例,将抗拔桩全部布置在筏基地基梁下,通过改变抗拔桩与柱荷载之间的距离,分析在抗压和抗浮两种不同工况下,桩-柱距离对筏基地基梁内力的影响,并找出最佳平衡点。
In the case of the same number of anti-static pile arrangement, the best anti-pressure anti-floating conditions will have their own way, and the distance between pile and column load acting point is an important factor . In order to intuitively study the influence of uplift pile and column load on the internal force of foundation girder, this paper combined with an engineering example, the anti-pile is placed under the raft foundation girder, by changing the distance between uplift pile and column load, analysis In two different conditions of compression and anti-floating, the effect of pile-column distance on the internal force of raft base girder, and find the best balance point.
