The invention discloses a post-construction-settlement-free rammed body with guide piles. The rammed body is characterized in that tube piles or prefabricated piles or wood piles with guiding functions are arranged at the lower end of a layered rammed body on soft soil or mudflat, wherein the guide piles are 10-100 centimeters in diameter, 2-15 meters in length and 1-10 meters in interval. Compared with the prior art, the rammed body has the advantages that remarkable superiority is realized, post-construction settlement of roads, dams, airstrips, goods yards and plant foundations on new marine reclamation lands or soft foundations can be prevented, and huge maintenance cost due to post-construction settlement in the prior art is saved; moreover, stone blocks and muck rammed into the rammed body can be rammed into the soft foundations downwards in an oriented way, and are prevented from greatly displacing laterally, so that 20-30 percent of muck is saved, and the cost is lowered. The rammed body is suitable for the projects of dams, express highways, yards, runways and the like on marine reclamation lands and soft foundations in China.
