A slope deep-buried shear-resistant pile supporting structure design method based on a plane sliding method
The invention discloses a slope deep-buried shear-resistant pile supporting structure design method based on a plane sliding method. The implementation process of the slope deep-buried shear-resistant pile supporting structure design method comprises the following steps: the diameter D of a deep-buried shear-resistant pile and the arrangement position and the arrangement distance s of the deep-buried shear-resistant pile on a slope are preliminarily determined; a row of shear-resistant piles in the longitudinal direction and a slope within the calculation width range of the shear-resistant piles are selected as calculation units, the number of the shear-resistant piles is set to be m rows according to the form of a sliding surface, and the horizontal projection length of strip blocks containing the piles is s; stress analysis is performed on the calculation units by adopting a plane sliding method, thus considering the anti-sliding force provided by the anti-shearing capability of the steel bars, calculating the cross sectional area As of the steel bar bundles required by each anti-shearing pile when the safety coefficient of the slope is Fs, and carrying out configuration of the steel bar bundles; and finally, according to the checking calculation of the uplift bearing capacity of the anchoring body, the length of the shear-resistant pile bed rock anchoring section and the length of the sliding body embedding section are calculated. The invention has good operability, economy is considered on the premise that safety is guaranteed, the construction period can be shortened, and the possibility of disasters is reduced.
本发明公开了一种基于平面滑动法的边坡深埋抗剪桩支护结构设计方法，其实施过程如下：初步确定深埋抗剪桩的直径D及其在边坡上的布置位置和布置间距s；选取纵向一列抗剪桩及其计算宽度范围内的边坡作为计算单元，根据滑面形式，设置抗剪桩数量为m排，且包含桩的条块水平投影长度为s。采用平面滑动法对计算单元进行受力分析，考虑由钢筋抗剪能力提供的抗滑力，计算边坡在安全系数为Fs时各抗剪桩所需钢筋束横截面积As，由此进行钢筋束的配置。最后根据锚固体抗拔承载力验算，计算抗剪桩基岩锚固段长度和滑体埋入段长度。本发明具有较好的可操作性，在保证安全的前提下兼顾经济性，且有利于节省工期，减小灾害发生的可能性。
