城市道路杂填土路基处理方法探讨

Discussion on the Treatment Method of Urban Road Miscellaneous Fill Subgrade

由于杂填土强度低、压缩性高的特性,在杂填土上修筑的道路路基如果未经处理,将会产生路基沉降、失稳的情况,因此需对杂填土进行处理。文章首先对杂填土性质和沉降类型进行阐述,然后对常见杂填土路基的处理方法进行阐述,最后分别结合具体的工程实例,详细分析换填法和CFG桩复合地基法在杂填土路基处理中的应用,探讨这两种路基处理方法的应用细节,以供相关人员参考。

Because of the low strength and high compressibility of miscellaneous fill,if the road subgrade built on miscellaneous fill is not treated,it will cause subgrade settlement and instability,so it is necessary to treat the miscellaneous fill.This paper first expounds the properties and settlement types of miscellaneous fill,and then expounds the treatment methods of common miscellaneous fill subgrade.Finally,combined with specific engineering examples,the application of replacement method and CFG pile composite foundation method in the treatment of miscellaneous fill subgrade is analyzed in detail,and the application details of these two subgrade treatment methods are discussed for the reference of relevant personnel.
