摘　　要：毛细饱和区的存在,使得有效自重应力的计算相对烦琐。尤其在考察有效自重应力分布时,很难直接绘制出各土层的分布曲线。为解决上述问题,以包含毛细饱和区的各土层有效自重应力计算为例,推导得出了可以快速计算土层中有效自重应力的方法,解释了毛细饱和区土体有效自重应力变化的本质。应用该方法,可以快速、高效地计算、绘制土层中有效自重应力的分布,对于土力学毛细饱和区相关知识点的理解和应用起到了积极的作用。The existence of capillary saturation zone makes the calculation of effective self weight stress relatively cumbersome. Especially when investigating the distribution of effective self weight stress, it is difficult to draw the distribution curve of each soil layer directly. In order to solve the above problems, taking the calculation of effective self weight stress of each soil layer including capillary saturation zone as an example, this paper deduces a method that can quickly calculate the effective self weight stress in soil layer, and explains the essence of the change of effective self weight stress of soil in capillary saturation zone. Using this method, the distribution of effective self weight stress in soil layer can be calculated and drawn quickly and efficiently, which plays a positive role in the understanding and application of relevant knowledge points in capillary saturation zone of soil mechanics.
