Summary: | To disclose a method and device for predicting pulling force of a pile foundation, and an electronic apparatus.SOLUTION: The method comprises the steps of: dividing a soil body around a pile foundation into multiple micro units along a vertical direction and determining a subsidence depth of the soil body using a vertically applied stress received by each soil body node; obtaining a soil sample at the subsidence depth of the soil body and generating a creep model regarding a confining pressure, a vertical stress, and a time change of a part of the micro unit by fitting based on triaxial creep test results of the soil sample; performing bilinear interpolation of the confining pressure and the vertical stress for a part of the creep models of the micro units to obtain the creep models of all the micro units; and calculating the soil body subsidence at a target time of each soil body node based on the creep model of each micro unit and determining the pulling force of the pile foundation by performing load transfer calculation using the soil body subsidence at the target time of each soil body node.SELECTED DRAWING: Figure 1
【課題】杭基礎引き下げ力の予測方法、装置及び電子機器を開示する。【解決手段】杭基礎の周囲の土壌体を鉛直方向に沿って複数のマイクロユニットに分割し、各土壌体節点が受けた鉛直方向付加応力を利用して土壌体の沈下深さを決定するステップと、土壌体の沈下深さでの土壌サンプルを取得し、土壌サンプルの三軸クリープ試験結果に基づいて、マイクロユニットの一部の拘束圧、鉛直方向応力及び時間変化に関するクリープモデルをフィッティングにより生成するステップと、マイクロユニットの一部のクリープモデルに対して拘束圧と鉛直方向応力の双線形補間を行って、全てのマイクロユニットのクリープモデルを得るステップと、各マイクロユニットのクリープモデルに基づいて各土壌体節点の目標時刻での土壌体沈下を計算し、各土壌体節点の目標時刻での土壌体沈下を利用して荷重伝達演算を行うことにより、杭基礎の引き下げ力を決定するステップと、を含む。【選択図】図1 |
