Stability Analysis of Subgrade Slope Filled with Construction Waste
In order to clarify the slope stability of the subgrade filled with construction waste recycled materials,this pa-per systematically analyzes the slope stability by using the standardized simplified Bishop method and the strength reduction finite element method according to the commonly used subgrade section forms in Tianjin.The analysis results show that lime mixed with soil stabilized brick is a good subgrade filler.When the upper and lower roadbeds are filled with construction waste,the safety factor of slope stability with a subgrade height of 3 m can meet the specification requirements.The strength reduction method and double strength reduction method is adopted to analyze and find that when the slope height is 3 m,the slope stability safety factor is all about 1.07.
