【摘要】：以黄河下游应急抢险和小水河道整治为研究背景,以重复组装式导流桩坝施工高压射水插桩和黄河下游土质为研究对象,利用D-P屈服准则简化土体模型,并建立射水插桩破土有限元模型,对简化后的有限元模型进行插桩过程的仿真分析。通过改变不同射水速度来观察破土有限元模型的沉桩过程,对不合理的射水插桩设计参数进行优化、筛选,得出最佳的射水速度为10 m/s。
[Abstract]:Taking emergency rescue and regulation of small water channel in the lower reaches of the Yellow River as the research background, the soil model is simplified by using D-P yield criterion to simplify the soil model, taking the high pressure water ejection pile and the soil quality of the lower Yellow River as the research objects in the construction of the reassembled diversion pile dam. The finite element model of soil breakage is established, and the simulation analysis of the simplified finite element model is carried out. The piling process of the soil breaking finite element model is observed by changing the different water ejection velocities, and the design parameters of the unreasonable water ejecting piles are optimized and screened, and the optimum water ejection velocity is obtained to be 10 m / s.
