贝佳亚连接线项目泥灰岩边坡破坏形式和处理措施研究

Study on the Damaged Form and Treatment Measures of Marl Slope in Bejaia Connecting Link Project

通过对贝佳亚连接线泥灰岩边坡破坏工点的破坏形式、发生原因以及处理措施的研究,发现滑塌是泥灰岩的主要破坏形式,岩层不良产状、坡面水下渗是泥灰岩边坡滑塌的重要原因。同时,实践证明,反压回填对于滑塌治理可以起到良好的效果。

Through the study of the failure form,cause and treatment measure of the marl slope of the Bejaia connecting line,it is found that the collapse is the main failure form of the mud rock,and the poor occurrence of rock stratum and the water infiltration on the slope are the important reasons for the collapse of marl slope.At the same time,the practice has proved that the back pressure backfill can play a good effect on the landslide control.
