【摘要】 根据三角形分布条形荷载作用下的土中应力计算公式,对作用于地表面的梯形分布荷载(或长宽比L/B≥10)引起的土中任一点附加竖向应力进行了计算,解决了土力学教材中计算公式过于复杂以及通过查表计算带来的误差和麻烦,具有一定的实用价值。更多还原

【Abstract】 Based on a theoretical formula of additional stress in soil on the action of triangle distributed load,additional stress in soil under trapezoid distributed load is calculated.The presented method is simple and better than in the soil mechanics reference books in which the formula seems to be complicated.It raises work efficiency and has practical significance.更多还原
