公路路基施工是整个公路施工工程的关键所在,稍有偏差,将给整个工程埋下质量隐患。例如遇到软基、井、墓穴等,如果不进行特殊处理,会引起施工后沉降或不均匀沉陷,路面纵横断裂,平整度下降,导致行车颠簸等,严重影响公路的正常使用,大大缩短道路的使用年限,造成大量的人力、物力、财 Highway subgrade construction is the key to the entire highway construction project, a slight deviation, will lay the quality hidden dangers for the entire project. For example, if soft foundation, well, grave, etc. are encountered, settlement or uneven subsidence after construction, vertical and horizontal breakage of the pavement and decline of flatness will be caused if no special treatment is carried out, which will cause traffic jolting etc. seriously affecting the normal use of the road and greatly shortening the road Of the service life, resulting in a large amount of manpower, material and financial resources
