摘　　要：随着城市的发展,拆除危旧房产生的建筑垃圾越来越多,含有大量建筑垃圾的杂填土的角色也在发生变化,可能成为人工地基或边坡。由于杂填土岩性的特殊性,在进行杂填土边坡支护时如何正确选择合适的支护方案是岩土工程面临的难点,这既是挑战又是机遇。论文对杂填土工程特性及压力分散型锚杆的工作特性和适用范围、作用机理及影响因素进行分析,通过工程实例,在杂填土边坡中采用压力分散型注浆锚杆进行支护并进行了锚杆基本试验,得出采用压力分散型注浆锚杆在杂填土边坡中进行支护是可行的,为杂填土边坡支护提供了新思路。With the development of the city,more and more construction waste is generated from the demolition of dilapidated houses.The role of miscellaneous fill which contains a lot of construction waste is also changing,and it may become artificial foundation or slope.Because of the special lithology of miscellaneous fill,it is a challenge and an opportunity for geotechnical engineering to choose a proper supporting scheme when carrying out miscellaneous fill slope support.Based on the analysis of the engineering characteristics of miscellaneous fill and the working characteristics,applicable range,action mechanism and influencing factors of pressure dispersed anchor rod,and the basic testing of the bolt is carried out,it is feasible to use pressure dispersed anchor rod to support miscellaneous fill slope,which provides a new idea for supporting miscellaneous fill slope.
