| Abstract: | The effect of backfill soil gravity amplified coefficient K on the design of highway reinforced concrete slab culvert is explored,and considering the excess compressive stress on the subbase,the concept of proper compation of soil is presented.During the design of reinforced concrete slab culvert structure,optimizing the foundation and application of the foundation trench installation technology are suggested to minimize or eliminate the effect of backfill soil gravity amplified coefficient K on the design of highway culvert. |

| Keywords: | coefficient K monolithic foundation foundation trench installation |
