- Abstract:
-
New prestressed pipe pile is presented on the basis of analysis of the characteristics of traditionalroekfill groins. Take Huayuankou for example, the eombination of the orthogonal experiment principle of thespur dikes sructure design, the overall displacement law with the parameters change of spur dikes is analyzedby FLAC3D finite difference code. The numerical results show that spur dikes of the horizontal displacement olthe contribution of primary and secondary order as follows: the seour depth of pile length > flow rate > pilespacing and pile diameter > contacts beam size; under the operalion conditions of flood flow 4 000 m’, watervelocity of 3 m/s, the seour depth is 16m operating conditions, the spur dikes structure program of the pilelength 25m 0.6m pile spacing, pile diameter is 600 mm, contact beam size is 0. 6 m x0.6 m is optimal, tothe safely factor of strength reduction method is 1.32.
