连续排列大圆筒筒后静止土压力的空间计算方法

Research on the Three-dimensional Computing Method of Static Outer Earth Pressure of Buried Large-diameter Cylinder

通过理论分析指出了连续排列大圆筒筒外壁曲面对土压力分布的影响 ,在土压力计算中应用空间计算理论 ,并引入了平衡拱体积、形状系数与圆筒直径关系的经验计算式。

Based on theoretical analyses,the influence of outer surface of cylinder on the earth pressure distribution is discussed.A three-dimensional theory is introduced in compution earth pressure and empirical formula concerned with relationship among the shape factor,the balance arch volume and the cylinder diameter is also provided.
