边坡形状是影响崩塌的因素之一，通过现场统计资料分析认为坡度、坡高和坡面形态对边坡崩塌的影响很大，故利用崩塌模拟实验进行不同坡度、不同坡面形态的对比试验，观测了边坡内部孔隙水压力随时间的变化过程和土体移动量随时间的变化规律，并对崩塌的形式和部位进行了定性描述。从而为进一步建立边坡崩塌预测模型和确定防灾对策提供了科学依据。 The shape of the slope is one of the factors that affect the collapse. According to the statistical analysis of the site, it is considered that the slope, slope height and slope shape have a great influence on the slope collapse. Therefore, the comparison experiment of different slope and different slope morphology , The change process of pore water pressure over time and the variation of soil mass with time were observed, and the form and location of the collapse were qualitatively described. Which will provide a scientific basis for further establishment of slope collapse prediction model and determination of disaster prevention measures.
