摘　　要：公路路基路面设计中,软基是十分棘手的一个问题,通常软基会引发公路路基路面沉降、变形,甚至会导致裂缝和路面坍塌等一系列问题,严重影响公路的正常使用。因此,有效处理软基问题是公路路基路面设计的关键。本文以积石山县银川至小关二级公路建设工程为例,分析该段路面的软基危害与问题处理方法,并提出几项软基处理技术,包括回填土软基处理技术、强夯法、深层水泥搅拌桩处理、轻质土路堤填筑技术以及表层排水软基处理技术。最终根据公路路基路面的设计情况,选择对应的软基处理技术,以期能够为国内公路工程建设提供借鉴。In the design of highway subgrade pavement,soft foundation is a very difficult problem,usually soft foundation will cause a series of problems such as settlement and deformation of highway subgrade pavement,and even lead to cracks and pavement collapse,which seriously affects the normal use of highway.Therefore,effectively dealing with the problem of soft foundation is the key to the pavement design of highway subgrade.Taking the construction project of Yinchuan-Xiaoguan secondary highway in Jishishan County as an example,this paper analyzes the soft foundation hazards and problem treatment methods of this section of the pavement,and proposes several soft foundation treatment technologies,including backfill soft foundation treatment technology,strong compaction method,deep cement mixing pile treatment,lightweight soil embankment filling technology and surface drainage soft foundation treatment technology.Finally,according to the design of highway subgrade pavement,the corresponding soft foundation treatment technology is selected,in order to provide a reference for domestic highway engineering construction.
