| 摘 要： | 在MELAN积分的思想上,通过积分法详细完整推导了在水平向线荷载下、任意泊松比下的土中应力公式,通过比较发现,当线荷载作用在地基表面时,任意泊松比下的土中应力公式等同于泊松比为0.5时的应力表达式.同时,鉴于国内土力学教材中无此荷载下的应力泡图形,给出了应力泡的详细绘制方法,为工程中地基中的应力分布形式的判断提供方便.

| Abstract: | Based on Melan integral, integral method was used to deduce the stress formula of soil under vertical line load and arbitrary Poisson＇ s ratio. The results indicated that when the line loads act on the ground surface, the stress formula of soil under arbitrary Poisson＇ s ratio is equal to the formula under Poisson＇ s ratio （0.5）. Because domestic soil mechanics textbooks have no such stress bubble graphics, a detailed mapping of stress bulbs under vertical liner load was given, which provide convenient for the judgment about the stress distribution form in engineering foundation |
