REINFORCEMENT METHOD OF WEAK GROUND, AND REINFORCEMENT SUPPORT DEVICE FOR WEAK GROUND
To provide a reinforcement support information for reinforcing by properly driving a reinforcement steel material into a weak ground, to reduce labor of a person in charge carrying out a reinforcement method and to decrease cost, and to quickly provide a reinforcement method in which safety is secured when concentrated load is applied to a weak ground in a short-term.SOLUTION: Reinforcement steel material dimension data can be set as adjustable variable numbers. Based on a setup instruction of a work person in charge, reinforcement steel material dimension data (cross section width dimension×reinforcement steel material length) is set. The set reinforcement steel material dimension data is changed in order, and frictional resistance force Qfri is calculated from an acquisition formula of frictional resistance force Qfri, and deformation earth pressure resistance force Wr is calculated from an acquisition formula of deformation earth pressure resistance force Wr. An increment Δqu of soil bearing capacity is calculated from an acquisition formula of an increment Δqu of soil bearing capacity. A soil bearing capacity of a ground after reinforcement is calculated from Tq=qa+Δqu. From kinds and dimension data of reinforcement steel materials satisfying Tq≥q, number of reinforcement steel materials within work steel plates are obtained.SELECTED DRAWING: Figure 6
【課題】軟弱地盤に補強鋼材を適切に打ち込むことで補強するための補強支援情報を提供して、補強方法を実施する担当者の負担を軽減して費用の削減を図り、軟弱地盤に短期的に集中荷重が作用した場合に安全性が確保された補強方法を迅速に提供する。【解決手段】補強鋼材寸法データを可変可能な変数として設定可能であって、作業担当者の設定指示に基づいて、補強鋼材寸法データ（断面幅寸法×補強鋼材長さ）を設定し、設定された補強鋼材寸法データを順次変更設定して、摩擦抵抗力Ｑfriの取得式から摩擦抵抗力Ｑfri及び変形土圧抵抗力Ｗrの取得式から変形土圧抵抗力Ｗrを演算し、地耐力度の増加量Δquの取得式から地耐力度の増加量Δquを演算し、補強後の地盤の地耐力度Tqを、Tq ＝qa＋Δquから演算し、Tq ≧ｑ を満足させる補強鋼材の種類及び補強鋼材寸法データから作業鋼板幅内補強鋼材本数を取得する。【選択図】図６
