Method for rapidly obtaining bearing capacity of foundation pile based on reverse self-balancing pile testing method
The invention discloses a method for rapidly obtaining the bearing capacity of a foundation pile based on a reverse self-balancing pile test method, which adopts abaqus software to carry out reverse self-balancing pile test simulation, and comprises the following steps of: firstly, establishing a reverse self-balancing pile test model, then endowing each part of the model with a corresponding material attribute parameter, assembling each part in an overall coordinate system, and finally establishing a reverse self-balancing pile test model; a proper initial distance between an upper pile and a lower pile is reserved, then an analysis type is selected in the analysis step module, a contact interface type is set in the interaction module, a boundary condition is set in the load module, loading is carried out according to a reverse self-balancing pile testing method, and a load displacement curve is obtained; and obtaining the bearing capacity of the foundation pile according to a calculation method of a reverse self-balancing pile test method. A complex and long test pile is not needed, an in-situ engineering pile test is also not needed, the engineering period is greatly shortened, and the construction efficiency is improved.
本发明公开了一种基于反向自平衡试桩法快速获得基桩承载力的方法，采用abaqus软件进行反向自平衡试桩模拟，首先建立反向自平衡试桩模型，然后对模型的各个部件赋予相应的材料属性参数，将各个部件装配在总体坐标系中，预留上下桩之间合适的初始间距，之后在分析步模块中选取分析类型，相互作用模块中设置接触界面类型，之后载荷模块中设置便边界条件，按照反向自平衡试桩法进行加载获得载荷位移曲线，根据反向自平衡试桩法的计算方法得到基桩承载力。本发明无需复杂漫长的试验桩，也无需原位的工程桩试验，大大降低了工程周期，提高了施工效率。
