【摘要】 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。更多还原

【Abstract】 According to analysis of statistical data on spot, the slope shape is considered as the most direct factor influencing the slope avalanches. Especially, the grade, height and pattern of slope are much important. Based on simulation of different grades and patterns of slopes. The variation law of pore water pressure and soil moving quantity on the slope, qualitative mode and position of slope avalanches are discussed. The article contributes the scientific basis of developing avalanche and disaster forecasting systems.更多还原
