【摘要】：以黃河下游應(yīng)急搶險和小水河道整治為研究背景,以重復(fù)組裝式導(dǎo)流樁壩施工高壓射水插樁和黃河下游土質(zhì)為研究對象,利用D-P屈服準則簡化土體模型,并建立射水插樁破土有限元模型,對簡化后的有限元模型進行插樁過程的仿真分析。通過改變不同射水速度來觀察破土有限元模型的沉樁過程,對不合理的射水插樁設(shè)計參數(shù)進行優(yōu)化、篩選,得出最佳的射水速度為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.
