线性回归法求解盾构机壳体任意点周围土压力

Investigation into random-point soil pressures on shield machine case using linear regression method

以往在计算盾构机周围土体作用力时,大多采用四分圆法来近似地反映盾构机周围土体作用,但不能求解盾构机壳体任意点周围土压力.提出了一种线性回归法来研究盾构机圆周上任意点的土体作用力,为盾构机周围土体作用力的研究提供了新的思路.

Previously,the quadrant method is approximately applied for soil actions towards shield machines.Hence,the random-point-surrounded soil pressures cannot be solved.Particularly,a linear regression method is proposed to provide a new option.
