EARTHQUAKE-RESISTANT DESIGN SYSTEM FOR COMPOSITE SOIL PILE FOUNDATION
To provide an earthquake-resistant design system for a composite soil pile foundation that can reduce the period required for designing piles and soil improvement bodies when the soil improvement bodies are provided around the piles.SOLUTION: An earthquake-resistant design system 10 for a composite soil pile foundation comprises specification setting means 11 for setting specifications of a soil improvement body and a pile, soil response analysis means 12 that dynamically analyzes a one-dimensional model of only the soil and estimates the soil response, soil displacement estimating means 13 for estimating soil displacement at a position corresponding to the pile by applying the estimated soil response to a finite element model in which only the soil improvement body is provided in the soil and statically analyzing it, pile stress estimating means 14 that estimates the stress of the pile at the time of an earthquake by applying the horizontal force acting on a pile cap and the estimated soil displacement to a beam spring model whose analysis target is the pile, and design verification means 15 to verify whether the estimated pile stress is below a threshold value.SELECTED DRAWING: Figure 2
【課題】地盤改良体が杭の周囲に設けられる場合における、杭及び地盤改良体の設計に要する期間を低減可能な、複合地盤杭基礎の耐震設計システムを提供する。【解決手段】複合地盤杭基礎の耐震設計システム１０であって、地盤改良体と杭の仕様を設定する仕様設定手段１１と、地盤のみの１次元モデルを解析対象として動的解析し、地盤応答を推定する地盤応答解析手段１２と、推定された地盤応答を地盤中に地盤改良体のみが設けられた有限要素モデルに与えて静的解析することにより、杭に相当する位置の地盤変位を推定する地盤変位推定手段１３と、杭頭に作用する水平力と、推定された地盤変位とを、杭を解析対象とする梁ばねモデルに与えて、地震発生時の杭の応力を推定する杭応力推定手段１４と、推定された杭の応力が閾値以下であるか否かを検証する設計検証手段１５と、を備える。【選択図】図２
