IN-GROUND STRESS CALCULATING METHOD
To provide an in-ground stress calculating method, the in-ground stress immediately below an arbitrary point, in an isotropically homogeneous semi-infinite ground.SOLUTION: An in-ground stress calculating method includes: dividing a loading range of an evenly distributed load into rectangular loads in a rectangular load division portion; calculating in-ground stress immediately below an end of each divided rectangular load in an in-ground stress calculation portion; and adding up and superimposing the in-ground stress calculated for each divided rectangular load in an in-ground stress superimposition portion. In the in-ground stress calculation portion, an absolute value is added to the ratio of a loading width and a depth of Newmark's in-ground stress calculation formula. In the in-ground stress superimposition portion, when adding and subtracting the in-ground stress calculated for each divided rectangle, the in-ground stress is multiplied by a sign function of a value obtained by multiplying extensions of two sides of the divided rectangle.
【課題】等方均質な半無限地盤において、任意地点直下の地盤内応力算定方法を提供することである。【解決手段】等分布荷重の載荷範囲を長方形荷重に分割する長方形荷重分割部と分割した各長方形荷重端部直下で地盤内応力を算定する地盤内応力算定部、分割された長方形荷重ごとに算定した地盤内応力を合算して重ね合わせる地盤内応力重ね合わせ部を有することを特徴とし、前記地盤内応力算定部において、ニューマークの地盤内応力算定式の荷重載荷幅と深度の比率に絶対値をつけることと前記地盤内応力重ね合わせ部において、分割した長方形ごとに算定した地盤内応力を加算・減算する際に、地盤内応力の前に分割した長方形の２辺の延長を掛けた値の符号関数を乗じることを特徴とする。
