<p><P>PROBLEM TO BE SOLVED: To provide a civil engineering structure that can reduce the amount of sediment etc., to be removed when forming a flat surface for installation on a slope and also reduce acting external force. <P>SOLUTION: An excavation surface 92 having a larger tilt angle than a slope 90 is formed in a part of the slope 90, and a civil engineering structure 100 installed on a flat surface 91 formed connecting with the excavation surface 92 includes a steel-made frame 110, a rear surface 2 which forms the steel-made frame 110 and is close to the excavation surface 92 being inclined to approach the excavation surface 92 more at a higher position (rear-surface tilt angleθ1>90°). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
