Mechanical property simulation method for large-diameter annular foundation pile
The invention discloses a mechanical property simulation method for a large-diameter annular foundation pile. The mechanical property simulation method comprises the steps of determining a model experiment correlativity and scheme, building a model pile, preparing a soil material around the model pile, preparing a model box, installing and loading experimental equipment, analyzing a model experiment result and comparing and analyzing the result. The method has the beneficial effects that the settlement, the bearing capacity and the compression amount of the pile body are described, and the result rule of a numerical simulation experiment is used as reference guidance, multi-angle demonstration and comprehensive consideration are performed, so that the condition that the bearing performance and the mechanical performance of the annular pile can reach the same degree as those of a traditional solid pile is finally judged; in order to verify that the mechanical property of the annular pile changes along with the thickness-diameter ratio K, in the thickness-diameter ratio range set in the subject, the concrete saving range is 0%-68%, and it is fully proved that the annular pile can meet the requirements for saving a large number of building materials and reducing the construction cost under the condition that it is guaranteed that the bearing capacity meets the requirements.
本发明公开了一种大直径环型基桩的力学性能模拟方法，包括确定模型实验相关关系及方案、建立模型桩、制备模型桩周土材料、制备模型箱、实验设备安装及加载、模型实验结果分析和结果对比分析。本发明的有益效果是：通过对桩身沉降，承载力和压缩量三个方面进行描述，并以数值模拟实验的结果规律做参考指导，多角度论证，综合考量，最终判定环型桩、承载性能和力学性能均可以达到与传统实心桩的相同的程度，并应用在实际工程中，为验证环型桩的力学性能随厚径比K的变化，在本次课题设定的厚径比范围中，混凝土的节省量范围为0％～68％，充分证明环型桩能够在保证承载力满足要的情况下，做到节省大量建筑材料，降低施工成本的要求。
