摘  要:
以PP织物袋梯田田坎为研究对象,通过人工降雨及弦式土压力盒实测田坎土压力相结合的方法,分析了陕南秦巴山区PP织物袋梯田筑坎土的压力分布,进而探究了导致田坎产生滑塌、鼓肚等破坏形式的原因。研究结果表明,对于不同工况修筑的梯田,其田坎土压力分布曲线呈现出不同的形式。暴雨和连阴雨是导致PP织物袋梯田垮坎的关键性因素。

摘  要:
The research of soil pressure distribution on the terraced field ridge of polyprophylene bags was undertaken with the test of soil pressure using the soil pressure boxes under artificial rainfall and the cause of slumping and bulging of retaining wall of terraced field with polypropylene bags in Qinba Mountain in Southern Shaanxi Province was explored.The results showed that the distribution curve of soil pressure on the terraced field ridge varied with different building conditions,and the heavy rain and continuous rain are the key factors of the collapse of the terraced field ridge.
