PROBLEM TO BE SOLVED: To provide an embarkment reinforcement structure preventing collapse of a slope of embarkment. SOLUTION: An embarkment 3 is provided on a ground 13. The embarkment has a substantially isosceles trapezoidal sectional shape, and a slope 7a is provided on a side surface thereof. An end part 5a is provided at the lower end of the slope 7a. A pile foundation 15a is built within the ground 13, and the pile foundation 15a includes a wall body 9a built to contact with the end part 5a. An oblique wall 11a is provided on the slope 7a, and the lower end of the oblique wall 1a is connected with the wall body 9a. Namely, since the embarkment 3 is enclosed by the oblique wall 11a and the wall body 9a, the slope 7a is never collapsed sideward even at the time of earthquake or heavy rain.
