摘要:
在分析传统堆石丁坝特点的基础上,提出了新型预应力管桩丁坝.以花园口为例,结合正交试验原理对丁坝结构进行设计,采用FLAC3D有限差分程序对其进行数值模拟,分析预应力管桩丁坝结构参数变化对丁坝整体位移的影响规律.数值计算结果表明,对丁坝水平位移的贡献主次顺序为:冲刷深度＞桩长＞流速＞桩间距＞桩径＞联系梁尺寸；在洪水流量为4 000 m3,水流速度为3 m/s,冲刷深度为16 m的工况下,桩长为25 m,柱间距为0.6m,桩径为600 mm,联系梁尺寸为0.6m×0.6m的丁坝结构方案最优,强度折减法计算丁坝安全系数为1.32.
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.
