边坡工程长短组合抗滑桩应用的数值模拟研究

Study on numerical simulation of a combination of long and short anti slide piles

利用数值模拟的方法,模拟不同工况组合,探究长短组合抗滑桩在边坡工程中的可行性及协同工作特性。结果表明:长短桩协同的形式充分发挥了桩体的抗弯性能,相比普通等长抗滑桩能够减少工程量,节约成本,且对坡体的安全系数并无显著影响。

Feasibility and characteristics of cooperative work in slope engineering by a combination of long and short anti slide pile are explored using the method of numerical simulation to simulate a combination of different working conditions. The resuits show that the form of long and short piles can give full play to the flexural behavior of the pile, and can reduce the amount of the project and save the cost as compared with the ordinary equal length anti slide pile, and has no significant influence on the safety factor of the slope.
