METHOD OF EVALUATING SAFETY OF RETAINING WALL, SAFETY ASSESSMENT PROGRAM OF RETAINING WALL AND SAFETY EVALUATION SYSTEM OF RETAINING WALL
PROBLEM TO BE SOLVED: To provide a method of evaluating the safety of a retaining wall which evaluates the safety of the retaining wall with high accuracy in the case where a ground surface shape of a back face of the retaining wall is of a complicated shape or when considering the adhesive force to the soil of the back face of the retaining wall, and a safety assessment program of a retaining wall and a safety evaluation system of a retaining wall.SOLUTION: A method of evaluating the safety of a retaining wall for evaluating the safety of a retaining wall, comprises the steps of: determining a slip form occurring on a back face of the retaining wall; deciding the calculation method of earth pressure according to the determined slip form; calculating an earth pressure received from the back face of the retaining wall by using an iterative algorithm of the present invention by a different approach from the conventional calculation method (trial wedge method and improved trial wedge method); evaluating the safety of a retaining wall using earth pressure; and graphically showing change of earth pressure over the entire calculation range.SELECTED DRAWING: Figure 3
【課題】擁壁背面の地表面形状が複雑な形状を呈している場合や擁壁背面の土質に粘着力を考慮する場合において擁壁の安全性を高精度に評価する擁壁の安全性評価方法、擁壁の安全性評価プログラムおよび擁壁の安全性評価システムを提供することを課題とする。【解決手段】擁壁の安全性を評価する擁壁の安全性評価方法であって、擁壁背面に発生するすべり形態を判定し、判定されたすべり形態に応じて土圧の計算方法を決定し、従来計算法（試行くさび法・改良試行くさび法）と異なるアプローチで、擁壁の背面から受ける土圧を本発明の反復法のアルゴリズムを用いて演算するものであり、その土圧を用いて、擁壁の安全性を評価し、併せて計算範囲全体における土圧の変化状況を図化することを特徴とする。【選択図】図３
