Abstract

A method of load reduction on buried culvert using an EPS block is disclosed. A culvert foundation is constructed at a place where a culvert will be buried, and the culvert is put on the foundation, and then, both sides of the culvert are banked with filling earth. EPS blocks are paved in multiple layers on the top surface of the culvert, or geosynthetics and an ESP block are paved on the culvert, and then, filling earth is banked on the geosynthetics or the ESP block and a final ground level is compacted. As a result, compression occurs from the EPS block, deformation of the inside earth is caused artificially, and arching is generated. Accordingly, the method has vertical earth pressure reduction effect, thereby preventing an increase in the section of the culvert due to overburden of the banked earth and an increase in vertical load due to a settlement amount of the culvert buried on the weak ground and a relative settlement difference of surrounding earth, and improving durability of the buried culvert.
