微型组合抗滑桩联系梁的受力及效果分析

运用MIDAS/GTS软件,以“白石洞滑坡”治理工程为基础,建立数值分析模型,分析微型抗滑桩治理滑坡时,有、无联系梁的两种情况下边坡的稳定性及微型桩的抗滑机理。通过分析得知,当有联系梁时,边坡的稳定系数更高,桩受压力作用比无联系梁时小,桩顶、联系梁承受拉力作用。通过联系梁的受力分析,得到联系梁横梁主要受压力作用,纵梁承受拉力作用。

Study on the Force and Effect of Connection Beams of Micro-combined Anti-slide Piles

Based on the White Stone Cave Landslide treatment project, a numerical analysis model is established by MIDAS/GTS software to study on the stability of slopes and anti-slide mechanisms of micropiles under two conditions:connected by beams or not. The results suggested that the stability coefficient of the slope was higher and the bearing pressure of the piles was smaller when the micropiles were connected by beams due to the fact that the pile top and connection beams were sharing the pressure and tension. Through the analysis of the force on the connection beams, it was found that the transverse beams mainly bear the pressure, while the longitudinal beams bear the tension.
