拱形组合抗滑桩结构分析研究

Research about the structure of arc-shaped combination of anti-slide pile

根据目前滑坡处治中抗滑桩的应用现状,提出了一种新型结构形式的抗滑桩——拱形单元组合抗滑桩。首先,运用PKPM软件对比计算了单排直线形、双排直线形与拱形单元组合抗滑桩在相同作用力下的桩顶位移大小,然后,用ANSYS软件对计算结果进行了校核。结果显示,拱形单元组合抗滑桩应用了拱的优良受力特性,在提高抗滑桩整体刚度的同时,较大地减小了桩顶位移,具有较好的市场应用前景。

According to the application of anti-slide pile in landslide treatment, a new structure type of anti-shde pile which named arc- shaped element combination anti-shde pile is proposed. Firstly, this thesis applies the software PKPM to contrast the displacement on the top of the pile of arc-shaped element combination anti-slide pile with sing-row line anti-slide pile and double-row line anti-slide pile under the same forces. After examined the results by ANSYS ,the are-shaped element combination anti-slide pile is shown that this new type of anti-slide pile has full use of the excellent characteristics of arch and increased the global stiffness of anti-slide pile. At the same time, the displacement on the top of this new type structure is much smaller than the other two kinds of common piles, therefore ,it has good market foreground.
