Trough calculation, it is obviously reasonable to ignore the effect of joint bending stiffness and consider it as a hinge joint in calculation.
通过比较可知,在计算中忽略节点抗弯性能对结构的影响,把节点看成铰接是合理的,而忽略节点局部平动刚度对结构的影响,把节点看成理想铰接却引起了较大的误差。

After analysizing the results of SSRFEM and centrifugal model test, someconclusions are drawn that, the depth of slip surface implies that the Bishopssimplied method cannot indicate the true failure mechanism for the slopes reinforcedwith piles. The rate of safety factors decreases with the pile spacing decreasing, andthe salty factor of the slopes is the largest when the reinforced piles are installed in themiddle of the slopes, regardless of pile head confining conditions, and the deflection,maximum bending moment and shear force in the reinforced piles in the criticalcollapse are the biggest meantime. The fixed and hinged head condition of the pilesresults in smaller bending moment in the piles than that in unrotated and free headcondition, therefore the restrained pile head condition is recommended in the design.
3不同特性与工况下抗滑桩与土体相互作用的数值分析与离心模型试验研究表明:采用简化Bishop法计算得到的滑动面不能反映抗滑桩加固边坡的破坏机理,抗滑桩设置在边坡中部和减小桩间距有利于提高边坡稳定安全系数,而此时抗滑桩在边坡临界破坏时的挠度、最大弯矩和最大剪力相对较大;桩头固定、铰接与桩头自由、平移相比,所加固边坡的整体水平位移及边坡临界破坏时抗滑桩的最大弯矩相对较小,而稳定安全系数则较大,因此在进行抗滑桩设计时应尽量选择桩头固定与铰接的型式,或对桩头进行锚固以改善抗滑桩的受力特性,提高边坡的稳定安全性状。

And destruction usually occurs on angle.(2)Around the keyhole, the stress centralizes, column" edge opt to inflects in local.(3)The change of friction coefficients or bolt pretension forces can"t affect the performance of top-and-seat angel connections so much.(4)The parameters of angel influence joints performance greatly.
破坏一般是由于顶角钢上应力过大,形成塑性铰而导致的;(2)柱翼缘在与顶角钢相连的螺栓孔周围,存在应力集中,容易导致局部屈曲;(3)材料抗滑移系数的改变和螺栓预拉力的大小对于节点受力性能的影响并不明显;(4)角钢参数的改变对节点的各项性能影响显著,增加角钢厚度,节点的强度、刚度和延性都能得到明显的提高;增加角钢长度,节点的强度和刚度也有较大的提高,延性则略有下降;(5)柱轴压比过大时,节点的承载力、刚度以及变形能力明显下降;(6)螺栓中心线到角钢肢背距离增大时,节点的强度和刚度有所下降,但延性略有增加。

Main conclusions of this paper are listed as bellows: First hinge line is not particular in the complete-system, but the close bar on it will generate great stress while the initial stress is imported. So the structural shape has not only great relations with the position set of the hinge line, but also maximum impacts on the deformation of the whole body. Equal to the support part of jacks, the circumference of the fist hinge line will generate the greatest impacts while exchange.
