本文通过对发生在天津新港和深圳妈湾港的两个不同类型的实际破坏的软粘土土坡的计算和分析 ,发现这两个土坡在破坏形式和破坏原因上都存在着差异 ,且破坏后的地形、地貌也有很大的差别 .有限元计算表明这两类土坡的应力场和位移场的分布各自具有不同的特点 ,进行土坡稳定验算也应采用不同的方法 ,这些都说明这两个土坡的破坏存在着不同的机制 .此结果不仅对工程实践具有指导作用 ,而且对研究土坡的破坏机理 ,探索计算土坡稳定的适用计算方法都有现实意义
Based on the calculation and analysis of two different types of soft clay soil slopes that actually occurred in Xingang, Tianjin and Mawan, Shenzhen, it is found that there are differences between the two types of soil slopes in the form of damage and the reason of damage, After the terrain and topography are also very different. Finite element analysis shows that the distribution of stress field and displacement field of the two types of soil slopes have different characteristics, and different methods should be adopted for stability checking of soil slopes, which shows that There are different mechanisms for the destruction of the two soil slopes, which not only can guide the engineering practice, but also have practical significance for studying the failure mechanism of soil slopes and exploring the applicable calculation methods for calculating the slope stability
