Reinforcement Technology for Cracking and Sliding of Expressway Roadbed Slope
In response to the frequent occurrence of slope diseases on highways at present,a reinforcement technology for cracking and sliding of highway roadbed slopes was studied.Based on the basic information of the highway subgrade slope project,comprehensively analyze the main causes of cracking and sliding diseases in the subgrade slope.Starting from the aspects of anchorage treatment,ecolog-ical reinforcement treatment and anti-slide pile reinforcement treatment,the repair and management scheme of cracking and sliding diseases is designed.Apply reinforcement treatment technology,and complete the repair work.The results show that,for 10 random ex-pressway subgrade slope measuring points,under normal conditions,rainstorm weather and earthquake conditions respectively,the slope stability safety factors after reinforcement construction are greater than the minimum standard 1.25 of the actual project.After rein-forcement,the shear strength of the soil has increased by 25%on average,the compression modulus has increased by 15%on average,and the permeability coefficient has decreased by 30%on average.
