Soil slope deeply-buried shear-resistant pile supporting structure design method based on simplified Bishop method
The invention discloses a soil slope deeply-buried shear-resistant pile supporting structure design method based on a simplified Bishop method, and the implementation process is as follows: the arrangement position of deeply-buried shear-resistant piles on a slope is preliminarily determined, the row pitch and the pile spacing are s, and the pile diameter is D; a row of shear-resistant piles and a slope in a calculation width range of the shear-resistant piles are selected as a calculation unit, a sliding mass part of the calculation unit is divided into n strip blocks according to a sliding surface form, i is used for representing any strip block, the number of the shear-resistant piles is set to be m rows, and when i = k + 1-k + m, the strip blocks containing the shear-resistant piles are represented; stress analysis is performed on each block on the basis of a simplified Bishop method, by considering the anti-sliding force provided by the shear resistance of the steel bars, calculating the cross sectional area Asp of the steel bar bundle required by the shear-resistant pile when the safety coefficient of the slope is Fs, configuration of the steel bar bundle can be performed. 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.
本发明公开了基于简化毕肖普法土质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在边坡上的布置位置，排距和桩间距均为s，桩径为D；选取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，将该计算单元的滑体部分划分为n个条块，用i表示其中任意条块，设置抗剪桩数量为m排，当i＝k+1～k+m时表示包含抗剪桩的条块。基于简化毕肖普法对各条块进行受力分析，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时抗剪桩所需钢筋束横截面积Asp，由此进行钢筋束的配置。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。
