摘要
抗滑桩与滑坡体的相互作用是一个复杂系统。利用专门设计的安置有光纤和电测器件的物理模型试验装置,通过改变抗滑桩的几何尺寸、布置间距以及滑体的滑移面角等有关参数,研究抗滑桩与滑坡体之间的相互作用,获得了在不同桩体几何尺寸、间距以及滑体滑移面角β等参数情况下抗滑桩的受力状况和滑体作用在抗滑桩上的滑坡推力函数q(H),进一步揭示了抗滑桩与滑体之间的相互作用机制。
The interaction mechanism between anti-sliding piles and landslide mass is complex. In this paper, this interaction mechanism was investigated through physical model tests of anti-sliding piles and landslide mass, in which FBG sensors and common electric sensors were installed as measurement devices. Main parameters such as pile sizes, pile spaces and angle of sliding surface were investigated. Their relationship with the resistance force function was correlated. Some special landslide phenomena and pile bearing status were observed, and the interaction mechanism was understood.
